Work Step by Step
$157 \frac{1}{2} \div 4 \frac{3}{8}$ cords can be made
Estimate
$158 \div 4 = 39 \frac{2}{4} = 39 \frac{1}{2}$
Solve
$157 \frac{1}{2} \div 4 \frac{3}{8}$
Convert to improper fractions
$\frac{315}{2} \div \frac{35}{8}$
Multiply by reciprocacl of divisor
$\frac{315}{2} \times \frac{8}{35}$
Reduce by common factors of 2 and 35 then multiply.
$\frac{9}{1} \times \frac{4}{1}$ = 36
36 pull cords can be made.
Check
$36 \times 4 \frac{3}{8}$ = $36 \times \frac{35}{8}$ = $\frac{1260}{8}$ = $157 \frac{1}{2}$
