What is 81/85 Divided By 2/1

Solving $\frac{81}{85}\div\frac{2}{1}$

• Rewrite the Division as Multiplication by the Reciprocal:

$\frac{81}{85} \div \frac{2}{1} = \frac{81}{85} \times \frac{1}{2}$

• Multiply the Numerators: $81 \times 1 = 81$
• Multiply the Denominators: $85 \times 2 = 170$
• Form the New Fraction: $\frac{81}{85} \times \frac{2}{1} = \frac{81}{170}$

Simplify - Since $\frac{81}{170}$​ is already in its simplest form (there are no common factors between $81$ and $170$ other than $1$), this is the final answer.

Answer $\frac{81}{85}\div\frac{2}{1} = \frac{81}{170}$
