Joseph's flock has 55% more sheep than goats. What is the
ratio of goats to sheep in the flock?

20 : 31

Step-by-step explanation:

If one calls the number of goats in the given situation (x), then one can model the situation. Since the number of sheep is 55% more than the number of goats, then one can say that the number of goats times (1.55) is equal to the number of sheep.

goats : sheep

x : 1.55x

Simplify, divide by (x)

1 : 1.55

Multiply by (100) to make both numbers whole numbers,

100 : 155

Simplify, divide by (5)

20 : 31
