Question

Bonita said that the product of 5/6 × 1 2/3 is 7/3.

How can you tell that her answer is wrong?

A-The answer must be less than 5/6.
B-The answer cannot be an improper fraction.
C-5/6 of a number cannot be greater than the number.
D-The denominator cannot be the same as one of the factors.

Answer 1

C-5/6 of a number cannot be greater than the number.

Explanation:

5/6 × 1 2/3 is 7/3.

First let's solve it:

• Convert 1 2/3 to an improper fraction

1 2/3 = (1 *3) + 2 / 3 = 5/3

• Multiply the fractions

5/6 × 5/3 = 25/18

A is wrong because the answer is not less than 5.6

B is wrong because the answer is an improper fraction.

D is wrong because the denominator is the same as one of the factors.

Therefore it has to be C.

2/3 * 1 = 2/3

Therefore how can 5/6, which is less than 1, multiply by 2/3 and get a greater answer.

Answer 2

The answer is 25/18, not 7/3.

Explanation:

1 2/3=5/3

5/6*5/3=25/18
