Question

To increase an amount by 7%, what single multiplier would you use?

Answer 1

you would use 0.7 to find the answer

Answer 2

percent means parts out of 100
7%=7/100=0.07

so what increasing by 7% of itself is is

original+original times 7%
we can actually do this and apply distributive property
original times 1+original times 0.07=original times (1+0.07) or original times 1.07

so the single multiplier is 1.07
