Question

A single tennis court is 75% the width of a doubles tennis court. The singles court is 27 feet wide. How wide is the doubles court?

Answer 1

X = 75% * y

Where 'x' is the single tennis court width, and 'y' is the doubles tennis court width.

Plug in what we know:

27 = 75% * y

75% = 0.75

27 = 0.75 * y

27 = 0.75y

Divide 0.75 to both sides:

y = 36

So the doubles court is 36 feet wide.

Answer 2

So,

The single tennis court is three-fourths the width of the double tennis court.

The singles tennis court is 27 ft. wide.

Multiply 27 by the reciprocal of three-fourths.
$27 * \frac{4}{3} = \frac{108}{3}\ or\ 36 ft.$

The doubles tennis court is 36 ft. wide.
