The bill for a pizza was 14.50 . charles paid for 3/5 of the bill. show two ways to find how much he paid

Well, if the pizza total was $14.50 and if there were 5 people in total, you'd do 14.50 divided by 5 to get $2.09 per person. If Charles paid 3/5 then do 2.09 times 3 to get $6.27.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
