What will come in place of the question mark(?) in the following questions ?
We need to find the value of $$\frac{5}{9} of 315+\frac{3}{7} of 455$$. Let us find the value of the components first.
$$\frac{5}{9} \times 315 = 175$$
$$\frac{3}{7} \times 455 = 195$$
Hence, their sum equals $$175 + 195 = 370$$
