To solve this question, we first need to convert both of these values into mixed numbers. 5
becomes
and 4
becomes
. Now we have to find a LCD. An LCD for 4 and 8 is 8, so now we have to change
into something over 8.
becomes
when you multiply the fraction by the form of 1
. 34 + 43 = 77, so our answer is 77/8 which simplifies to
9 
.
18. -500 + 250 = -250
19. -550 - 300 = - 850
20. 116 - (-50) = 116 + 50 = 166
21. 2500 + 1800 - 2200 = 2100
