What is 70/81 Divided By 1/7

Solving $\frac{70}{81}\div\frac{1}{7}$

• Rewrite the Division as Multiplication by the Reciprocal:

$\frac{70}{81} \div \frac{1}{7} = \frac{70}{81} \times \frac{7}{1}$

• Multiply the Numerators: $70 \times 7 = 490$
• Multiply the Denominators: $81 \times 1 = 81$
• Form the New Fraction: $\frac{70}{81} \times \frac{1}{7} = \frac{490}{81}$
