Question

You are making costumes for a play. You have sewn 9 costumes. If you are 30% finished, how many costumes are you sewing?

Answer 1

here's the solution : -

if i made 9 costumes and it is 30 % of total costumes, so lets take the total number of costumes as x

so, by above statement we get,

$\frac{30}{100} \times x = 9$

=》

$x = 9 \times \frac{100}{30}$

=》

$x = 30$

so, total number of costumes = 30 costumes.
