What is 81/85 Divided By 8/1

Solving $\frac{81}{85}\div\frac{8}{1}$

• Rewrite the Division as Multiplication by the Reciprocal:

$\frac{81}{85} \div \frac{8}{1} = \frac{81}{85} \times \frac{1}{8}$

• Multiply the Numerators: $81 \times 1 = 81$
• Multiply the Denominators: $85 \times 8 = 680$
• Form the New Fraction: $\frac{81}{85} \times \frac{8}{1} = \frac{81}{680}$
