Question

If the sum of 2 number is 72 find the numbers are in the ratio 5:7

Answer 1

$\huge\color{Blue}{Hey\: Mate!!}$

here is your answer:

Let the two numbers be 5x and 7x

5x+7x=72

12x=72

X=72\12

X=6

Hence, the two numbers are:

5x=5×6=30
7x=7×6=42

Verification:
30+42=72

Therefore the two numbers are 30 and 42.

hope it helps you!!

Answer 2

$\huge\mathfrak{Heya}$

$\mathsf{Given \ ratio \ = \ 5:7}$

$\mathsf{Let \ the \ numbers \ be \ 5x \ and \ 7x.}$

$\mathsf{A/q}$

$\mathsf{Sum \ of \ these \ two \ numbers \ = \ 72}$

$\mathsf{5x + 7x = 72}$

$\mathsf{12x = 72}$

$\mathsf{x = 6}$

$\mathsf{1st \ number \ = \ 5x \ = 5 × 6 = 30}$

$\mathsf{2nd \ number \ = \ 7x \ = \ 7 × 6 = 42}$

$\huge\mathbb{Hope \ this \ helps.}$
