THE PRODUT IF TWO RATIONAL NUMEBR IS -15/7 IF ONE I FTGEM IS -10/21 FIND OTHER

Answer 1

Heya !!

Let other rational number be X.

Product of two rational numbers = -15/7

-10/21 × X = -15/7

X = -15×21/ 7 × -10

X = (-3 × 3 ) / ( -2 )

X = 9/ 2

Other rational number = X = 9/2

Answer 2

Hi , there !!

Let the one number be X

X × -10 /21= - 15/ 7

X = -10 / 3 × -15

=> 4.5
