Question

Question 1(a) :

Write the fractions appropriately as additions or subtractions:

Answer 1

To find out the fraction a given figure represents we follow the steps given below:

(i) Identify the number of equal parts in which the figure is divided

(ii) Number of parts that are coloured or shaded

The fraction that they represent = $\frac{\text{Number of parts coloured}}{\text{Total number of equal parts}}$

Hence, the above figures represent the fractions $\frac{1}{5}$, $\frac{2}{5}$ and $\frac{3}{5}$ respectively.

Now, $\frac{3}{5}$ > $\frac{1}{5}$, $\frac{2}{5}$.

Therefore the fractions $\frac{1}{5}$ and $\frac{2}{5}$ will be added.

$\frac{1}{5}+\frac{2}{5}=\frac{1+2}{5}=\frac{3}{5}$
