Answer 2

Question should be:

• The LCM and HCF of two numbers are 90 and 9 respectively . if one number is 18 , then the other number is

ANSWER:

• Other number= 45

GIVEN:

• LCM of two numbers is 9.
• HCF of two numbers is 90.
• First number = 18

TO FIND:

• Second number

SOLUTION:

Formula:

=> LCM * HCF = Product of two number.

Here :

LCM = 9

HCF = 90

First number = 18

Let the second number be x

Putting these values in formula we get;

=> 9*90 = 18*(x)

=> (9*90)/18 = x

=> 45 = x

Other number = 45.
