For example if you have multiple numbers with the letter a at the end you will want to add. 7a + 8a would be 15a. Same for subtraction. If you have an equation with multiple letters. For example 4a+9b it will stay 4a and 9b. Make sure to do pemdas
The solution for this problem is just adding and subtracting fractions. We all know how to add and subtract function because our teacher since high school teach us how to. P(Q or R) = P(Q) + P(R) - P(Q and R) = 5/8 + 1/8 - 1/32 = 23/32
The answer to this question is 23/32.
72% of 500 is 360 sheets, if you used 10 sheets each week it would be 72%*5 --(10x8)= 280 sheets left
2748?? Your question is a little unclear
Happy studying ^_^
