Question 5.

\(\frac{8}{9}\) – \(\frac{4}{9}\) = ____

Answer:

\(\frac{8}{9}\) – \(\frac{4}{9}\)

The denominators of both the fractions are same.

So, we can subtract the numerators.

\(\frac{8}{9}\) – \(\frac{4}{9}\) = \(\frac{8-4}{9}\) = \(\frac{4}{9}\)

Question 6.

Area of a rectangle = l × w

A = 8 × 9

A = 72 sq. meters
