Solve 66=2*22/7r

$$66 = 2 \times \frac { 22 } { 7 } r$$

Solve for r

$$r = \frac{21}{2} = 10\frac{1}{2} = 10.5$$

Steps for Solving Linear Equation

Express 2\times \frac{22}{7} as a single fraction.

$$66=\frac{2\times 22}{7}r$$

Multiply 2 and 22 to get 44.

$$66=\frac{44}{7}r$$

Swap sides so that all variable terms are on the left hand side.

$$\frac{44}{7}r=66$$

Multiply both sides by \frac{7}{44}, the reciprocal of \frac{44}{7}.

$$r=66\times \frac{7}{44}$$

Express 66\times \frac{7}{44} as a single fraction.

$$r=\frac{66\times 7}{44}$$

Multiply 66 and 7 to get 462.

$$r=\frac{462}{44}$$

Reduce the fraction \frac{462}{44} to lowest terms by extracting and canceling out 22.

$$r=\frac{21}{2}$$
