may weighed 40kg last year. her weight increases to 45kg this year. what percentage of the
original weight is her new weight?
writte down the horizontal form and answer

 12.5%

Step-by-step explanation:

Use the percentage change formula:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
