Question

the product of two rational numbers is 2/15 if one of the number is minus 8 by 9 find that other number​

Answer 1

Step-by-step explanation:

Given,

Sum of Two rational no. = 2/15

First rational no. = -8/9. (Given)

Let the second rational no. be x.

ATQ,

-8/9 + x = 2/15

x = 2/15 -(-8/9)

= 2/15 + 8/9

= 6+40/45. (taking 45 as l.c.m.)

x = 46/45 (second rational no.)

Answer 2

Answer:

Let the other number be E

then, -8/9 × E = 2/15

so, E = 2/15 ÷ -8/9

=> E = 2/15 × -9/8

=> E = -3/20

hence, the other number is -3/20.
