Answer 1

Answer:

24 and 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
