percent of the marbles are white?

Answer:

20%

Step-by-step explanation:

given the info, let's add up all of the marbles we have so far

7 + 4 + 2 + 3 = 16 marbles

the rest are white and the total number of marbles in the bag are 20

16 marbles + white marbles = 20 marbles

there must be 4 white marbles

putting this in a fraction is 4/20

to put in percentage multiply by 100

4/20 × 100 = 20%
