Answer 1

Answer:

The value of m is 7 .

Step-by-step explanation:

Given -

$3, 18, m ,42$ are in proportion​

To find -

The value of m

Solution -

Proportion is a mathematical comparison between two numbers.

We can write given information as,

$\frac{3}{18}= \frac{m}{42}$

$\frac{3}{18}\times 42=m$

Divide 18 by 3 we get

$\frac{1}{6}\times 42=m$

Divide 42 by 6 we get

$m = 1 \times 7$

$m=7$

∴ The value of m is 7 .

×42=m

Divide 18 by 3 we get

2/6 42=m

6

1

×42=m

Divide 42 by 6 we get

m = 1 \t 7m=1×7

m=7m=7

∴ The value of m is 7 .

3/18 = m /42 .

1/6 = m / 42 .

m = 42/6

m = 7 .
