Question

If 6:36 :: x:72,What is the value of x ?​

Answer 1

Answer:

$\huge\bf\red{Answer}$

$= \frac{6}{36} = \frac{x}{72}$

$= 6 \times 72 = 36 \times x$

$= \frac{6 \times 72}{36}$

$= 6 \times 2 = x$

$= x = 12$

Answer 2

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

We have given 6:36::x:72

=>36×x=72×6

=>36x=432

=>x=432/36

=>x=12

x =12

Check

6:36::12:72

=>1:6::1:6

[12×6=72 & 6×6=36]

Therefore,the above values are in proportion ✓
