Question

Evaluate the following:
$(i) 7 \times \frac{3}{5}$ $(i i) 21 \times \frac{3}{14}$
$(i i i) 3 \frac{2}{5} \times 8$ $(i v) 5 \times 6 \frac{3}{4}$

Open in App

Solution

$(i) 7 \times \frac{3}{5} = \frac{21}{5} = 4 \frac{1}{5}$
$(i i) 21 \times \frac{3}{14} = \frac{9}{2} = 4 \frac{1}{2}$
$(i i i) 3 \frac{2}{5} \times 8 = \frac{17}{5} \times 8 = \frac{136}{5} = 27 \frac{1}{5}$
$(i v) 5 \times 6 \frac{3}{4} = 5 \times \frac{27}{4} = \frac{135}{4} = 33 \frac{3}{4}$
