If he can read 21 pages in 1 hour he can read 63 in 3 hours
Use PEMDAS:
P = parenthesis
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
First, start with the parenthesis:
(8.76 * 109)(6.52 * 10 - 3) / 13.27 * 105
(954.84)*(62.2) / 13.27 * 105
Then do ALL multiplication:
59,391.048 / 1,393.35
Now do all division:
42.62
So, your final answer is 42.62
