Question

Two numbers are in the ratio 4: 7. If their L.C.M. is 168, find the numbers.



please explain step by step​

Answer 1

Answer:

42

Step-by-step explanation:

It is given that Ratio between two numbers = 4: 7

LCM of two numbers = 168

Consider first number = 4x

Second number = 7x

Now the LCM of 4x and 7x=4×7×x=28x

By equating both the values 28x=168

So we get x=

28

168

=6

So the required numbers 4x=4×6=24

7x=7×6=42

Answer 2

Answer:

b ±√6, a = (4±7√6) / 7

Step-by-step explanation:

let a,b be the no

4:7

a:b = 4:7

a/b = 4/7

a = 4/7 b

axb = 168

(4/7)b = 168

4b = 168/7

b = 24/4

b= 6

a = 4/7×6

a = 24/7
