• 7/8

• 7/9

• 7/10

• 7/11

Answer explanation

To divide fractions, multiply by the reciprocal. Thus, 2/3 ÷ 6/7 = 2/3 × 7/6 = (2×7)/(3×6) = 14/18, which simplifies to 7/9. Therefore, the correct answer is 7/9.

Find the quotient 21 and 1 ¼

• 12 3/5

• 14 1/4

• 16 4/5

• 18 4/5

Answer explanation

To find the quotient of 21 and 1 ¼, convert 1 ¼ to an improper fraction: 5/4. Then, divide 21 by 5/4, which is the same as multiplying by 4/5. This gives 21 * 4/5 = 16 4/5, the correct answer.

Edith wants to cut pieces of ribbon 1/3 meter long from a piece of 5/6 meter. 

How many pieces can be cut?

• 2 1/2

• 3 1/4

• 4 1/2

• 5 1/3

Answer explanation

To find how many 1/3 meter pieces can be cut from 5/6 meter, divide 5/6 by 1/3. This is equivalent to multiplying 5/6 by the reciprocal of 1/3, which is 3/1. Thus, (5/6) * (3/1) = 15/6 = 2 1/2.
