What is 91/45 Divided By 4/1

Solving $\frac{91}{45}\div\frac{4}{1}$

• Rewrite the Division as Multiplication by the Reciprocal:

$\frac{91}{45} \div \frac{4}{1} = \frac{91}{45} \times \frac{1}{4}$

• Multiply the Numerators: $91 \times 1 = 91$
• Multiply the Denominators: $45 \times 4 = 180$
• Form the New Fraction: $\frac{91}{45} \times \frac{4}{1} = \frac{91}{180}$
