Question

7/10 of a wall is to be painted .Ramu has painted 4/10 of it.How much morr needs to be painted?

Answer 1

7/10-4/10=3/10
therefore 3/10 of it should be painted

Answer 2

Answer:

The portion of the wall to be painted  = $\frac{3}{10}$

Step-by-step explanation:

Given,

The portion of the wall to be painted = $\frac{7}{10}$th of the wall

The portion of the wall painted by Ramu = $\frac{4}{10}$

To find,

The portion needs to be painted

Solution:

The portion of the wall that needs to be painted = total portion of the wall to be painted -  the portion of the wall painted by Ramu

= $\frac{7}{10}$ - $\frac{4}{10}$

Since the denominators are the same, the difference of the fractions can be calculated by subtracting the numerators

= $\frac{7-4}{10}$

= $\frac{3}{10}$

The portion of the wall to be painted = $\frac{3}{10}$
