please answer my question its chapter name is fraction ​

Answer 1

Answer:

The fraction of his salary is still left with him is $\dfrac{3}{10}$

Step-by-step explanation:

Given,

• spends $\dfrac{2}{5}$ his salary on food
• $\dfrac{3}{10}$ on house rent, electricity, etc.

Let us take x be the remaining salary

So,

the sum of total salary = 1

x + $\dfrac{2}{5}$ + $\dfrac{3}{10}$ = 1

$\dfrac{10x+4+3}{10}$ = 1

10x + 7 = 10

10x =10 - 7

10x = 3

x = $\dfrac{3}{10}$
