there are 15 dogs and 17 cats. write the ratio of dogs to cats 3 different ways
i need help this thing is over due by a month
if there are 60 girls and 80 boys in the class, write the ratio of boys to total students
write 2 ratios that are equivalent to 3/4.
It costs $4.20 to buy a 12 ounce box of crackers. What is the unit cost? (cost per ounce)
It costs $5.10 to buy a 15 ounce box of crackers. What is the unit cost? (cost per ounce)
Looking at your last 2 answers, which box of crackers is the better buy? How can you tell?
If 1 in. = 2.54cm, how many cm are in 20 inches?
Do these ratios form a proportion? Yes or no? Show your work! 3/4 24/32
Are these ratios proportional? Yes or no? Show your work!
12/16 3/5
two ratios a/b and c/d are proportional if ad = bc
i found a video for it but thank you i worked it out
To write the ratio of dogs to cats three different ways when there are 15 dogs and 17 cats, you can use the following formats:
1) 15:17 (dogs to cats)
2) 15/17 (dogs to cats)
3) 15 dogs / 17 cats (dogs to cats)
To write the ratio of boys to total students when there are 60 girls and 80 boys in the class, you can use the following format:
1) 80/140 (boys to total students)
To find two ratios that are equivalent to 3/4, you can multiply or divide both the numerator and denominator of the fraction by the same number. Here are two examples:
1) Multiply 3/4 by 2: (3 * 2) / (4 * 2) = 6/8
2) Divide 3/4 by 2: (3 / 2) / (4 / 2) = 3/2
To find the unit cost (cost per ounce) for a box of crackers, you divide the total cost by the number of ounces.
For the 12 ounce box that costs $4.20, the unit cost is $4.20 / 12 ounces = $0.35 per ounce.
For the 15 ounce box that costs $5.10, the unit cost is $5.10 / 15 ounces = $0.34 per ounce.
To determine which box of crackers is the better buy, you compare the unit costs. In this case, the 15 ounce box has a lower unit cost of $0.34 per ounce compared to the 12 ounce box's unit cost of $0.35 per ounce. Therefore, the 15 ounce box is the better buy as it offers a lower cost per ounce.
To convert inches to centimeters using the conversion rate 1 in. = 2.54 cm, you multiply the number of inches by 2.54.
For 20 inches, the conversion is 20 inches * 2.54 cm/inch = 50.8 cm.
To determine if ratios form a proportion, you need to check if the two ratios are equal.
For the ratios 3/4 and 24/32:
- Simplify 3/4: Divide both the numerator and denominator by their greatest common divisor, which is 1. Therefore, 3/4 is already in its simplest form.
- Simplify 24/32: Divide both the numerator and denominator by their greatest common divisor, which is 8. (24/8) / (32/8) = 3/4.
Since both ratios simplify to 3/4, they are equal and thus form a proportion.
For the ratios 12/16 and 3/5:
- Simplify 12/16: Divide both the numerator and denominator by their greatest common divisor, which is 4. (12/4) / (16/4) = 3/4.
- Simplify 3/5: Divide both the numerator and denominator by their greatest common divisor, which is 1. Therefore, 3/5 is already in its simplest form.
Since the simplified ratios 12/16 and 3/4 are not equal, the ratios 12/16 and 3/5 are not proportional.
