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?

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 ...

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

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.

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

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.

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 ...

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?
