Question:
At a cricket test match $\frac{2}{7}$ of the spectators were in a covered place while 15000 were in open. Find the total number of spectators.
Solution:
Ratio of spectators in the open $=1-\frac{2}{7}$
$=\frac{5}{7}$
Total number of spectators in the open $=x$
Then, $\frac{5}{7} \times x=15000$
$\Rightarrow x=15000 \div \frac{5}{7}$
$=15000 \times \frac{7}{5}$
$=\frac{15000}{1} \times \frac{7}{5}$
$=\frac{15000 \times 7}{1 \times 5}$
$=\frac{10500}{5}$
$=21000$
Hence, the total number of spectators is 21,000
