Question

the products of two integers is 270 if one number is (-15)find the other number ​

Answer 1

Answer: -18

Step-by-step explanation: Well for starters we know it is going to be a negative number as a negative times a negative makes a positive number. By knowing this, we can tell that if we get a positive number as an answer, then we are miles off and have calculated it wrong. To calculate it we need to do the reverse operation, so if the equation right now is -15 x ? = 270, then the reverse operation would be 270/-15 = ?

So we need to do 270/-15, one simple way of doing this is 270/15 which is 18, and then flipping that answer to negative. So the answer for the other integer is -18.

Hope this helps.

Answer 2

Answer- The above question is from the chapter 'Integers'.

Integers: Negatives of natural numbers, 0 and all positive natural numbers are called integers.

Set of integers is denoted by Z.

Given question: The product of two integers is 270. If one number is -15, find the other number.

Solution: First integer = - 15

Let second integer be x.

According to the question, product of two integers is 270.

⇒ - 15 × x = 270

x = 270 ÷ (- 15)

x = -270/15

x = - 18

∴ The second number is - 18.
