Let x be number of widgets produced in 3 1/2 weeks.

The proportion therefore between the two ratios is


\frac{x\text{ widgets}}{3(1)/(2)\text{ weeks}}=\frac{1250\text{ widgets}}{1\text{ week}}

To solve for the number of widgets they can produce, multiply both sides by 3 1/2, to cancel out the denominator on the left side of the proportion.


\begin{gathered} 3(1)/(2)\text{ weeks}\Big(\frac{x\text{ widgets}}{3(1)/(2)\text{ weeks}}=\frac{1250\text{ widgets}}{1\text{ week}}\Big)3(1)/(2)\text{ weeks} \\ \cancel{3(1)/(2)\text{ weeks}}\Big{(}\frac{x\text{ widgets}}{\cancel{3(1)/(2)\text{ weeks}}}=\frac{1250\text{ widgets}}{1\cancel{\text{week}}}\Big{)}3(1)/(2)\cancel{\text{week}} \\ x\text{ widgets }=1250\cdot3(1)/(2)\text{ widgets} \\ x\text{ widgets }=1250\cdot3.5\text{ widgets} \\ x\text{ widgets }=4375\text{ widgets} \end{gathered}

Therefore, they can produce 4375 widgets in 3 1/2 weeks.
