A 3-yard-long ribbon was used to trim four dresses. Each dress used the same amount of ribbon. How much ribbon was used for each dress?
\(\frac{\mathrm{3} }{\mathrm{4}}\) yard.
1 yard.
\(\frac{\mathrm{2} }{\mathrm{3}}\) yard.
\(\frac{\mathrm{1} }{\mathrm{2}}\) yard.
Detailed Explanation
Convert the measurement to inches: 1 yard = 36 inches; 36 inches × 3 = 108 inches.
Divide the total number of inches by the number of dresses being trimmed to determine the length of each piece of ribbon: 108 inches ÷ 4 = 27 inches.
Convert the quotient (27 inches) to a fraction of a yard: \(\frac{\mathrm{27} }{\mathrm{36}}\) = 27 ÷ 36 = 75% = \(\frac{\mathrm{3} }{\mathrm{4}}\) of a yard.
