Answer 2

Answer:  All the ratios that are equivalent to 4: 5 are

2:2.5   3:3.75  and   8:10

Step-by-step explanation:  You can check by making fractions of the ratios.

4/5 = 0.8

2/2.5 = 0.8  Also, the values are each half of the given ratio.

8/10 = 0.8   and the values are double the numbers in the given ratio.

3:3.75   this one is not obvious at first, but each value is .75 or 3/4 of the numbers in the given ratio, and it passes the decimal equivalency test:

3/3.75 = 0.8
