Question

Write four ratios that are equivalent to the ratio 2: 5 . Explain why all of the ratios are equivalent.

Answer 1

Four ratios that are equivalent to 2:5 are 4:10, 6:15, 8:20, and 10:25. All of these ratios are equivalent because the 2 and the 5 are both multiplied by the same natural number (other than 1).
