this is an aops prealgebra 2 problem (I'm taking the course rn and it was the first problem in week 1.) so I'll give @Choff a hint instead of the answer.
try writing 0.025% as a fraction. What do you get?
btw, @Melody is wrong...
To add on to @Guests's, the question is asking for what A-B is. so A-B=4-2=2
start by converting 12 1/2% (0.125) as a common fraction -> 1/8
2000*1/8=250
this was posted twice but here is the answer
61/7=8 5/7 so the answer is 8
5666/2381
how many 2381s are in 5666? 2
what is 5666/2381 as a mixed number? 2 904/2381
1-0.4=0.6
then it becomes the equation 0.6x=16
divide both sides by 0.6 to get $26.67
363 minutes actually...but 364 is also fine
when we factor, we get 2*x+2*12=2x+24
start by converting 3 2/3 into a proper fraction -> 11/3
12*11/3=44
start by converting 2 1/2 into a proper fraction -> 5/2
20*5/2=50
