Question

The product of two rational numbers is –8/9.ifoneof them is 10/3 what is the other rational numbers ?

Answer 1

Answer:

The other required rational number is - 4 / 15.

Step-by-step explanation:

According to the given question, product of two rational numbers is - 8 / 9, one number is 10 / 3,

Let the other rational number be a,

Given,

     Product of both the numbers = - 8 / 9

= > a x 10 / 3 = - 8 / 9

= > a = ( - 8 / 9 ) / ( 10 / 3 )

= > a = - 8 / 9 x 3 / 10

= > a = - 4 / 3 x 1 / 5

= > a = - 4 / 15

Hence the other required rational number is - 4 / 15.

Answer 2

Answer:

Step-by-step explanation:

Given :- product of two rational numbers is -8/9.

One of the two rational number is 10/3

QUESTION :- To find other number.

→ let the other number be " z "

So

Z × 10/3 = -8/9

Z = -8/9 × 3/10

{ •°• on transposing 10/3 to RHS . Multiplication becomes division . -8/9 is divided by 10/3.on making it multiplication the fraction becomes reverse I.e 3/10.}

Z = - 4/15

» So the another number is - 4/15 .
