She uses 4/3 (1 1/3) pint of hair gel in 4 days

This problem may be easier to work if we convert the numbers to decimals. We do this by dividing the numerator by the denominator.
1/3=0.33

Now, we will do 0.33 x 4 to figure how how much Monica uses in 4 days. This is equal to 1.32. We can round this up to 1.33. You can put your answer in decimal or fraction form.

So, your answer is:
1.33 or 1 1/3.
