Question

A large bag of marbles are 1/5 red 30% green, and .35 of the marbles are blue. The rest are white. What % are white?

Answer 1

15%.

Explanation:

1/5 = 20%

0.35 = 35%

% white = 100 - 30 - 20 - 35

= 100 - 85

= 15%,

Answer 2

Explanation:

so 1/5 = 20%(red)

they tell you 30 % are green

and .35 = 35% are blue

so far you have 85% out of 100%

then you subtract 100%-85%=15%

we subtract by 100 because there is 100% in a whole
