15 people shared 65 1/2 acres of land. How much did each get?
beks73 [17]

You need to divide 65 1/2 by 15.

65 \dfrac{1}{2} \div 15 =

= \dfrac{131}{2} \div \dfrac{15}{1}

= \dfrac{131}{2} \times \dfrac{1}{15}

= \dfrac{131 \times 1}{2 \times 15}

= \dfrac{131}{30}

= 4 \dfrac{11}{30}

Each one got 4 \dfrac{11}{30} acres.
