Question

A rectangle measures 1 1/4 by 2 3/4 inches what is the area

Answer 1

let's firstly convert the mixed fractions to improper fractions, and then get their product.

`\stackrel{mixed}{1(1)/(4)}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}} ~\hfill \stackrel{mixed}{2(3)/(4)}\implies \cfrac{2\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{11}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{5}{4}\cdot \cfrac{11}{4}\implies \cfrac{(5)(11)}{(4)(4)}\implies \cfrac{55}{16}\implies 3(7)/(16)`
