How do I simplify this expression and justify each step ? 12 * 7 * 2/3 thank you ! ! ! (:
-
Multiply the 12 by the 7 first:
12 * 7 = 84
Multiply that by 2:
84 * 2 = 168
Divide that by 3:
168 / 3 = 56
12 * 7 = 84
Multiply that by 2:
84 * 2 = 168
Divide that by 3:
168 / 3 = 56

order of operations.
12 * 7 * 2/3
write down first operation, and do it, as you write down the rest without changing it.
12 * 7 * 2/3
84 * 2/3
write down next operation, and do it, and if any other parts left write them down without changing ...
84 * 2 / 3
168 / 3
write down next operation, and do it, and if any other parts left write them down without changing ...
56
is this what your teacher wants?
