Question

Sum of two rational numbers is -3.If one of them is 2/5,find the other

Answer 1

Step-by-step explanation:

LET THE OTHER NUMBER BE

$x$

so. ACCORDING TO QUESTION

$\frac{2}{5} + x = - 3 \\ \frac{ 2 + 5x}{5} = - 3 \\ 2 + 5x = - 15 \\ 5x = - 17 \\ x = \frac{ - 17}{5}$

Answer 2

Answer:

hey frnd here is your answer

Step-by-step explanation:

Let the two Rational Number be x and y

According to the question we can write-

x+y= -3 ( sum is -3)

x= 2/5 ( One of them is 2/5).

now put the value of x in x+y= -3.

x+y= -3

2/5+y= -3

y= -3-2/5

y= -17/5.

So your other Rational Number is -17/5.

Proof-

-17/5+2/5= -3

so Yes our answer is correct.

so your final answer is-

The other Rational Number is -17/5.

I hope you get the right answer
