Question

A pet shop sells only guinea pigs and hamsters. The ratio of guinea pigs to

hamsters in the pet shop is 5 : 6.
There are 30 guinea pigs in the pet shop. How many animals are there in
total??

Answer 1

To find the total number of animals, set up a proportion using the given ratio of guinea pigs to hamsters. Solve for the unknown number of hamsters, then add the number of guinea pigs to find the total.

Step-by-step explanation:

To find the total number of animals in the pet shop, we can use the given ratio of guinea pigs to hamsters. The ratio is 5:6, which means for every 5 guinea pigs, there are 6 hamsters. Since we know there are 30 guinea pigs, we can set up a proportion to solve for the number of hamsters:

5/30 = 6/x

Cross-multiplying, we get 5x = 180. Dividing both sides by 5, we find that x = 36. Therefore, there are a total of 30 guinea pigs + 36 hamsters = 66 animals in the pet shop.

Answer 2

66

Step-by-step explanation:

30 x (5+6) ÷ 5

(Cross out the common factor) 6 x (5+6)

Calculate the difference 6 x 11

Answer: 66

There you're asnwer is 66
