Answer:
2/3
Step-by-step explanation:
First, you figure out how many marbles are in total, which is the denominator. The total number of marbles is 30.
Then, you figure out how many marbles are blue, which is the numerator. There are 20 blue marbles.
Finally, you simplify the fraction. 20/30=2/3.
<span>A unit fraction is a fraction where the denominator is one, so the easiest way to write 4/5 as a sum of unit fractions is to use 1/5.
So the answer would be 1/5+1/5+1/5+1/5.
Add up all the numerators and put that over their like denominators to get 4/5!</span><span />
