Question

9. The product of two integers is -120. If one number is 15, find the other.​

Answer 1

Answer :-

• The required number is -8.

Step-by-step explanation ::

To Find :-

• The other number

Solution :-

Given that,

• The product of two integers is -120
• One of the number is 15

Let us assume the other number as y,

Therefore,

• y × 15 = -120

=> y × 15 = -120

=> y = -120 ÷ 15

=> y = -8

We got, The value of y as -8. Therefore, the required number is,

As we assumed the other number as y,

=> y

=> -8

Hence, the required number is -8.

Now, Verification

• y × 15 = -120

We have,

• L.H.S = y × 15
• R.H.S = -120

Evaluating L.H.S, by putting the value of y,

=> y × 15

=> -8 × 15

=> -120

Hence,

• L.H.S = -120 and
• R.H.S = -120

Therefore, L.H.S = R.H.S

Hence, Verified!
