3x:7x::24:56
=3:7::3:7
Yes they form proportion..
As 24/56 on dividing by 8 we get same as 3/7

Rachna111: thank you but you have not given the proper steps if the person does not know formula then how he or she will understand

Hi.

Good question... Keep progressing...

Here is your answer---

______________________________________
______________________________________

To check : 3x,7x, 24 and 56 are in proportion.

Checking-----
If the given numbers are in proportion then,

3x : 7x :: 24 : 56
Product of Means = Product of Extremes [If the numbers are in proportion]
7x * 24 = 3x * 56
168x = 168x

Since,L.H.S = R.H.S

The given numbers [3x,7x,24 and 56] are in proportion.
