This week for writing we had to make 3 slides showing: Add/Sub, Ratiors solving and Multi/Div. Our groups were: Me, Alice and bella. We made 3 slides for each. We decided to blog our unfinished work because we wont be able to blog it any sooner and beause it is the last day of the trem. This will teach you how to solve problems using Multiplacation, Dividing, Addition, Subtraction, and ratios.
