Question

LCM and HCF of two numbers are 9 and 90 respectively if one number is 18 find the other​

Answer 1

Answer:

Since, the product of the H.C.F. and L.C.M. of any two numbers is always equal to the product of those two numbers. However the same is not applicable to three or more numbers.

Therefore the answer will be 45

Step-by-step explanation:

Let the number x

Since, HCF * LCM = PRODUCT OF THE TWO NUMBERS

THEREFORE,

   9 * 90 = 18 * x

   810 = 18 * x

   810/18 = x

    x = 45

hope this answer will help you !

Answer 2

The answer is 45

Step-by-step explanation:

Let the other number be 'x'

HCF × LCM = Product of the two numbers

9 × 90 = 18 × x

810 = 18x

x = 810 ÷ 18

x = 45
