What is the width of a rug that is 36 1/4 square feet and 8 3/4 wide
blondinia [14]

Answer: 4\frac{1}{7} ft

<u>Step-by-step explanation:</u>

Area (A): 36\frac{1}{4} = \frac{4(36)+1}{4} = \frac{144+1}{4} = \frac{145}{4}

Length (L): 8\frac{3}{4} = \frac{4(8)+3}{4} = \frac{32+3}{4} = \frac{35}{4}

width (w): W

A = L x W

\frac{145}{4} = \frac{35}{4} x W

(\frac{4}{35})\frac{145}{4} = (\frac{4}{35})\frac{35}{4} x W

\frac{4(145)}{35(4)} = \frac{145}{35} = \frac{5(29)}{5(7)} = \frac{29}{7} = W

\frac{29}{7} = \frac{7(4) + 1}{7} = 4\frac{1}{7}
