Plz solve it plz all 11 ,12

Answer 1

11. Answer:

LCM = 300

Explaination:

We will learn the relationship between H.C.F. and L.C.M. of two numbers.

The product of highest common factor (H.C.F.) and lowest common multiple (L.C.M.) of two numbers is equal to the product of two numbers.

H.C.F. × L.C.M. = First number × Second number

10 * LCM = 3000

LCM = 300

12: Answer: Second number = 352

Explaination:

Given lowest common multiple (L.C.M.) = 1760

Highest Common Factor (HCF) =32

First Number = 160

We find the second number.

Use the relation:

H.C.F. × L.C.M. = First number × Second number

32*1760 = 160 * second number

Second number = 352
