(i)

(ii)

(iii)

(iv)

Answer 1

(i)

First, we change these fractions to fractions with the same denominator.

Thus, the denominator required should be a multiple of 3 and 2 = 3 × 2 = 6.

and

Now, is made up of 4 equal parts out of 6 equal parts and is made up of 3 such parts.

∴

Now,

(ii)

First, we change these fractions to fractions with the same denominator.

Thus, the denominator required should be a multiple of 5 and 6 = 5 × 6 = 30.

and

Now, is made up of 24 equal parts out of 30 equal parts and is made up of 25 such parts.

∴

Now,

(iii)

First, we change these fractions to fractions with the same denominator.

Thus, the denominator required should be a multiple of 3 and 5 = 3 × 5 = 15.

and

Now, is made up of 10 equal parts out of 15 equal parts and is made up of 9 such parts.

∴

Now,

(iv)

First, we change these fractions to fractions with the same denominator.

Thus, the denominator required should be a multiple of 3 and 10 = 3 × 10 = 30.

and

Now, is made up of 10 equal parts out of 30 equal parts and is made up of 9 such parts.

∴

Now,
