Answer 1

Answer:

35

Step-by-step explanation:

as the question said..3:15::7:x

ie,3/15=7/x

x=7*15/3

x=35..

Answer 2

The value of m = 35

Given :

3 , 15 , 7 and m are in proportion

To find :

The value of m

Solution :

Step 1 of 2 :

Form the equation

Here it is given that 3 , 15 , 7 and m are in proportion

By the given condition

3 : 15 = 7 : m

Step 2 of 2 :

Find the value of m

$\displaystyle \sf{3 : 15 = 7 : m }$

$\displaystyle \sf{ \implies \frac{3}{15} = \frac{7}{m} }$

$\displaystyle \sf{ \implies 3 \times m = 7 \times 15}$

$\displaystyle \sf{ \implies m = \frac{7 \times 15}{3} }$

$\displaystyle \sf{ \implies m = 35}$

The value of m = 35
