Answer:
4/3
Step-by-step explanation:
If 1/3 quart of paint covers 1/4 of a basketball field, multiply 1/3 by 4 (since the denominator of 1/4 is 4 and the denominators represents the amount of peices that you're dividing the court into.)
(Remember that 4 is the same as 4/1)
Now, multiply the numerators and denominators.
1 x 4 = 4
3 x 1 = 3
= 4/3
So, 4/3 quart of paint would cover the enitre basketball court. I hope this helps!
