Simplify the Numerical Expression $$\left( \frac { 7 } { 10 } + \frac { 2 } { 5 } \right) \left( \frac { 1 } { 9 } + \frac { 2 } { 3 } \right)$$

question 293

Short Answer

Simplify the numerical expression. Remember that fractions are not considered simplified unless they are reduced. $$\left( \frac { 7 } { 10 } + \frac { 2 } { 5 } \right) \left( \frac { 1 } { 9 } + \frac { 2 } { 3 } \right)$$
