Can someone plz expalin increase n decrease examplw would help


ok say if we have a question like a sweet costs 32 pounds and then in 2 weeks it is 45.50 pence, we do the new value DIVIDED by the original value then times by 100. So 45.5/32 then times by 100= 142.1875 so the new value increased by 42.1875% because 100 percent was the orignal percentage and now it is 142.1875 so the answer is 42.1875% INCREASE or u can round that to 1.DP 42.2%
and say if you have a sweet that costed 22 pound and in a month it became 12 pound. U would do 12/22 times by 100= 54.545 then do 100 percent take way 54.545 = 45.455 percent DECRESAE or 45.5 percent decrease to 1 D.P

Bob has one apple. Margret has two. Margret has 100% more apples than Bob does.
