(1/3+1/6)(1/3+1/6)-(-1/4+7/8).can You Help Me?
Answer:
According to the order of operations, you work the sums inside the parentheses first. Because the second one is one and the same as the first one, one answer serves for both.
(1/3 + 1/6) = (2/6 + 1/6) = (3/6) = (1/2)
The other parentheses evaluate to ...
(-1/4 + 7/8) = (-2/8 + 7/8) = (5/8)
So, the whole expression can now be written
(1/3 + 1/6)(1/3 + 1/6) - (-1/4 + 7/8) = (1/2)(1/2) - 5/8
= 1/4 - 5/8 (because we subsequent have to do the multiplication)
= 2/8 - 5/8 (choose a common denominator)
= -3/8 (perform the sum)
-3/8
-0.375
