okay so.. Roman has 2 red pencils in his backpack.. if this is 25% of the total number of pencils, how many pencils are in his backpack?? please use symbols like x as times and divide as... DIVIDE

Respuesta :

I think it's 25x4=100 and 100 divided by 4= 25. Every 2 pencils = 25% so you need 2 4 times.2x4=8. 8 is your answer
25%=.25
2(divided by).25=8

Another way to think of this is 

25% is equal to 1/4 (1 divided by 4)
so 
2=(1/4)xX
X/4=2
X=2*4
X=8

X is the total number of pencils in the backpack
