I tried the problem in different ways and I also got 1/8 so now I know that I was on the right track a little bit. So then the answer would be: The ratio of zebras to total animals is 1 zebra to every 8 animals-Would this be a correct interpretation?

Math
Can you explain this to me a little bit as to why you are saying 1/8?

Math
The local zoo has 3 lions, 4 elephants, 2 giraffes, 5 monkeys, and 2 zebras. What is the ratio of zebras to total animals? My Answer: I already know this 3x:4x:2x:5x:2x=16x So 16 total animals 16x=2 x=8 So then the ratio of zebras to the total number of animals is 8 Can you ...

So that is how I would interpret this then. This is my first year learning about ratios and it is kind of confusing. Thank you for your help

Math
Let me ask you this. You said to repeat the same steps for Ren so I understand when you put 10:8:20 then I understand that you reduced 10:8:20=5:4:10 So would it be 5x:4x:10x= 19x=40 x=2.10

Math
When I tried to answer this I got the following: Sinea=$3.33 was spent on souvenirs Ren=$2.50 was spent on souvenirs I do not know if I got the correct answers and am unsure how to explain why one person paid more money than the other.

Math
It was as follows: Sinea=Snacks $5.00; Games $8.00; Souvenirs $12.00 Ren=Snacks $10.00; Games $8.00; and Souvenirs $20.0

Math
Suppose Sinea and Ren each spend $40.00 on snacks, and each person spends money using the same ratios as on their last trip. Who spends more on souvenirs? Explain. Please help me with this.

Math
Or Ren would spend $39.00 on souvenirs?

Math
Actually I arrived at an answer for part a of $1.50

Math
No it would be $2.50 because I just figured out how to get to that answer but part a is still confusing a bit to me.

Math
For part b wouldn't the answer be just $2.00?

Math
Well if I do 12/8x26/1=312/8=39 How can that be correct?

Math
I understand how you put it in a different perspective 12/8 so if he spends 26 on games she must spend 12/8 x 26 would you put 26 as the numerator or denominator?

Math
I am actually changing my answer to part a. to $13.00 but I am still confused on part a and b

Math
Would the answer for part a. be $6.00

ty Ms. Sue:)

Math
I figured out what I did wrong. In multiplication you don't find the common denominator but in addition and subtraction you do. That is what I did wrong.

Question: 168.72/0.024=7.03 When I do this calculation on paper the above answer is what I get but when I do this calculation on a calculator I get 7,030.00 what I am doing wrong?

Math
I just figured it out. 3+2=5x12=60 This makes sense.

Math
I meant to put 12x2=24

Math
I understand now what you are saying 12 x 2=12 and then 12x3=36 but I thought I had to do 12x(x+x)would equal 60

Math
We can rewrite the expression 16 + 8 as 8x(2+1). Notice that 8 is the greatest common factor of 16 and 8. Use this same method to rewrite the expression 24 + 36 as the product of the greatest common factor of 24 and 36 and the sum of the remaining numbers. Answer: I added 24...

Math
I was wrong. The greatest number of students that can be in each row is 9 because there would be a total of 18 rows.

Math
9 rows with 8 boys each 9 rows with 10 girls each The greatest number of students that can be in each row would be 18

Math
I am thinking about this a bit more now I don't feel that my answer was right. It can't be 86 if there are 72 boys and 90 girls. I am going to play around with the numbers a bit and then post a different answer.

Math
Yes to me it does because you take the total number of people on the team and divide by 2

Math
There are 72 boys and 90 girls on a math team. For the next competition, Mr Johnson would like to arrange all the students in equal rows with only girls and only boys in each row. What is the greatest number of students that can be in each row? Answer: 72 + 90=162 162/2=86 Can...

The reason why I was asking is I printed out a paper to look out for key words in math word problems. Thank you for helping me solve the problem.

Math
What was the indicator in the word problem is what I am trying to figure out that told you multiple?

Math
The least common multiple of 30 and 40 is 120. How did you know that I need to find the least common multiple of 30 and 40. Would 120 be the answer? So both lights would change at the same time again after 120 minutes.

Math
Thank you for checking my work.

Math
2/8 plus 6/12= 6/24 + 12/24=18/24=9/12=3/4 Can you please check the above answer and tell me if I got this correct?

Math
So then based upon what you pointed out about simplest form from the first problem my answer would be 2 13/20 Is that correct?

Math
Add. Write the answer in simplest form 1 9/10 plus 3/4 19/20 plus 3/4= 38/20 plus 15/20=53/20=2.65 Please let me know if I got the correct answer or if I am doing anything wrong.

Math
I think I somewhat understand

Math
Add. Write the answer in simplest form. 1. 3/8 + 4/5= 3/8=15/40 4/5=32/40 15/40 plus 32/40=47/40 47/40=1.175 Please let me know if I got the correct answer or if I did something wrong.

Math
So what you did then and I understand now how you got 63/2 because of how you explained it. Then you take 63/2 x 44/3=2,772/6=462 So the total area of the wall that the pictures cover is 462 inches? My only other question is this- If you simplify 63/2 this equals 31.5 and if ...

Math
If I add (21/2 plus 21/2 plus 21/2) this equals 63/6=10.5 44/3=14.6 How did you get 462?

Math
Okay. I understand how to get 21/2 and how to get 44/3 because I converted the mixed fractions into improper fractions but I am confused on how you put (21/2)(44/3) + (21/2)(44/3) +(21/2)(44/3) how would I add these?

Math
Three pictures hang side by side on a wall. What is the total area of the wall that the pictures cover? Length is 10 1/2 inches, 10 1/2 inches, 10 1/2 inches Width 14 2/3 inches Would I need to add 10 1/2 plus 10 1/2 plus 10 1/2 and then multiply by 14 2/3 inches? Please ...

Math
So "of" indicates multiply What would indicate division in a word problem?

Math
