Question

What should be added to thrice the rational number-8/5 to get 4/7?​

Answer 1

Answer:

Step-by-step explanation:

This can be carried out in another order but I might start by obtaining the common denominator.

7*9=63 so that is our common denominator.

Transferring that to the question we get: 3(-56/63) and 36/63 as our base numbers so -168/63 and 36/63.

To -168, you need to add 204 to obtain 36.

Answer: 204/63 or 3 and 15/63 if you want a mixed number.

plzz mark as brainly..

Answer 2

Let the number to be added be x
Then According to question
X+3(-8/5)=4/7
X-24/5=4/7
X=4/7+24/5
On solving by taking LCM
X=5.6
