Question

Your teacher assigned 30 practice problems. You completed 15 on Monday and 10 more on Tuesday. What fraction of the 30 problems did you complete?

Answer 1

I completed 5/6 of the 30 practice problems.

Monday : 15 / 30
Tuesday : 10 / 30

Adding fractions.
Step 1. Make sure both fractions have the same denominator.
15 / 30 + 10 / 30  *the same denominator.

Step 2. Add the numerators and place the sum above the common denominator.
(15 + 10) / 30 = 25/30

Step 3. Simplify the fraction.
25/30 = 5/6
