96.54 - 89.63/96.54 + 89.63 ÷ 965.4 - 896.3/9.654 + 8.963 = ?

Answer: Option A

Given expression :
= $$\frac{(96.54-89.63)}{(96.54+89.63)}$$   × $$\frac{(9.654+8.963)}{(965.4-896.3)}$$
= $$\frac{(96.54-89.63)}{(965.4-896.3)}$$   × $$\frac{(9.654+8.963)}{(96.54+89.63)}$$
= $$\frac{(96.54-89.63)}{10(96.54-89.63)}$$   × $$\frac{(96.54+89.63)}{10(96.54+89.63)}$$
= $$\frac{1}{10}$$ × $$\frac{1}{10}$$
= $$\frac{1}{100}$$
= $$\frac{1}{{10}^2}$$
= 10 ^-2
