4/5 :21/29::7/10:? 1)49/100 2)59/107 3)107/59 4) 70/17 ​

Answer 1

2) 59/107 is correct answer

Step-by-step explanation:

$\frac{4}{5} : \frac{21}{29}$

4 * 4 = 16 + 5 = 21

(Square of 4 and add denominator, 5 of 4/5 to it.)

5 * 5 = 25 + 4 =29

(Square of 5 and add numerator, 4 of 4/5 to it.)

Thus we get 21 /29

$\frac{7}{10} : \; ?$

7 * 7 = 49 + 10 = 59

(Square of 7 and add denominator, 10 of 7/10 to it.)

10 * 10 = 100 + 7 = 107

(Square of  10 and add numerator, 7 of 7/10 to it.)

Thus we get 59/107
