Help with math hw plz help

1.)what percent of 56 is 49
2.)what percent of 80 is 32
3.)18 is 72 percent of what number
4.)42 percent of what number
thx for ur help

1) Divide 46 by 56 multpily by 100 = 87.5%
2) 40%

3) 25% (18x100/72)

use the formula:
whole (%) = part

so in number 1 the whole is 56 and the percent is unknown so p and part is 49. the formula looks like this 56(p)=49 then you would divide both sides by 56 and the answer is .875 which is 87.5 %

2) 80(p)=32
p= 40%

3) w(0.72)= 18
w=25

4) .... not the full question


w=

1) 87.5%
2) 40 %
3) 25
4) not enough information
