Question 75

The value of $$3\frac{2}{7} + 14\frac{4}{9} + 5\frac{3}{9}$$ is:

Solution

= $$3\frac{2}{7} + 14\frac{4}{9} + 5\frac{3}{9}$$

= $$\left(3+14+5\right)\left(\frac{2}{7}+\frac{4}{9}+\frac{3}{9}\right)$$

= $$22\left(\frac{2}{7}+\frac{7}{9}\right)$$

= $$22\left(\frac{18+49}{63}\right)$$

= $$22\left(\frac{67}{63}\right)$$

= $$23\left(\frac{4}{63}\right)$$
