Celeste completed 5/6 of her science problems. Her mom checked 2/3 of the assignment. What fraction of the assignment did her mom check.

5/9
1/3
5/4
1/6

To find the fraction of the assignment that Celeste's mom checked, we need to multiply the fractions representing the parts of the assignment completed.

Celeste completed 5/6 of the science problems.
Her mom checked 2/3 of the assignment.

Therefore, the fraction of the assignment checked by her mom is (5/6) * (2/3) = (10/18) = 5/9.

So the correct answer is 5/9.

To find the fraction of the assignment that Celeste's mom checked, we need to find the product of Celeste's progress (5/6) and her mom's progress (2/3).

To multiply fractions, we multiply the numerator by the numerator and the denominator by the denominator.

(5/6) * (2/3) = (5 * 2) / (6 * 3) = 10/18

The fraction of the assignment that Celeste's mom checked is 10/18. However, we can simplify this fraction to its simplest form by dividing the numerator and denominator by their greatest common divisor (which is 2 in this case).

10/18 = (10 ÷ 2) / (18 ÷ 2) = 5/9

Therefore, Celeste's mom checked 5/9 of the assignment.

To find out what fraction of the assignment Celeste's mom checked, we need to multiply the fractions representing each of their progress.

Celeste completed 5/6 of the assignment, and her mom checked 2/3 of Celeste's work.

To calculate the fraction of the assignment checked by Celeste's mom, multiply 5/6 by 2/3:

(5/6) * (2/3) = (10/18) = (5/9)

Therefore, Celeste's mom checked 5/9 of the assignment. So the correct answer is 5/9.
