I need theses answer quick please! (will mark brainliest) determine whether each pair of ratios are equivalent ratios.

1. 8/9, 72/81

2. 3/14, 21/98

3. 12/17, 50/85

Step-by-step explanation:

1. 8/9 = 72/81

common multiple is 9 gcf. 9x8=72. 9×9=81

2.3/14= 21/98.

gcf = 7 .

1. Equivalent

2. Equivalent

3. Not equivalent

Step-by-step explanation:

So basically for all of them you need to find a multiple for the numerator of the first fraction to see if it equals the numerator of the second fraction, and same goes for denominator.

For the first one, 8*9 is 72, and you must multiply the denominator with the same number you multiplied the numerator with, so 9*9 is 81, so it is equivalent.
