Question

the product of two rational number is 2/15.if one of the number is -8/9,find the other number? ​

Answer 1

Answer:

plz mark me on brainlist.

Step-by-step explanation:

x-8/9=2/15

x=2/15+8/9

x=18+120/135

x=138/130

x=69/65.

Answer 2

Step-by-step explanation:

Given that,sum of two rational numbers is 2/15

one of the number is -8/9

Let the other number be x

-8/9 + x = 2/15 (transposing -8/9 to RHS)

x = 2/15 + 8/9

LCM of 15 and 9 = 45

x = (2/15 × 45 + 8/9 ×45)/45

x = (6 + 40)/ 45

x= = 46/45

check:

= 46/45+(-8/9)

= 46/45 - 8/9

LCM of 45 and 9 = 45

= (46/45×45 - 8/9×45)/45

=( 46 - 40 )/ 45

= 6 / 45

= 2/15
