Question

Select all ratios equivalent to 5:3,
25:15
10:1
3:9

Answer 1

Explanation:

25:15 is equivalent to 5:3 because 25 is 5 times 5, and 15 is 5 times 3.

10:1 is not equivalent to 5:3 because the sides cannot be multiplied to get 10:1.

3:9 is not equivalent to 5:3 because 5:3 has a bigger numerator and a smaller denominator, while 3:9 has it swapped.
