Question

14 workers, working at the same pace, can lay 36000 bricks in one day. How many workers will be needed to lay 54000 bricks in the same period of time?

Answer 1

21 workers would be your answer.

Answer 2

`\bf \begin{array}{ccll} workers&bricks\\ \cline{1-2} 14&36000\\ x&54000 \end{array}\implies \cfrac{14}{x}=\cfrac{36000}{54000}\implies \implies \cfrac{14}{x}=\cfrac{2}{3} \\\\\\ 42=2x\implies \cfrac{42}{2}=x\implies 21=x`
