Subtract 1/4 from 3/4.

• 1/3

• 2/3

• 1/2

• 1/4

Answer explanation

To subtract 1/4 from 3/4, we need to find a common denominator, which is 4. Then, 3/4 - 1/4 = 2/4 = 1/2. Therefore, the correct answer is 1/2.

Multiply 2/3 by 4/5.

• 3/10

• 5/6

• 6/7

• 8/15

Answer explanation

To multiply fractions, multiply the numerators (2 * 4 = 8) and denominators (3 * 5 = 15) separately. Therefore, 2/3 * 4/5 = 8/15.

Divide 5/6 by 2/3.

• 1/2

• 3/4

• 2/5

• 5/4

Answer explanation

To divide fractions, multiply the first fraction by the reciprocal of the second. (5/6) ÷ (2/3) = (5/6) * (3/2) = 15/12 = 5/4, which is the correct answer.

Provide an example of unlike fractions.

• 4/5

• 1/2, 3/4

• 5/6

• 2/3

Answer explanation

The correct choice of unlike fractions is 1/2 and 3/4 because the denominators are different, which makes them unlike fractions.

Compare 2/5 and 3/5.

• 2/5 = 3/5

• 2/5 < 3/5

• 3/5 > 2/5

• 2/5 + 3/5

Answer explanation

To compare 2/5 and 3/5, we see that 3/5 is greater than 2/5 because the numerator is larger, indicating a larger fraction.

Compare 1/3 and 2/7.

• 1/3 < 2/7

• 1/3 > 2/7

• 1/3 < 2/7

• 1/3 = 2/7

Answer explanation

To compare 1/3 and 2/7, find a common denominator. Multiplying 1/3 by 7/7 gives 7/21, and 2/7 is already in the form 2/7. Since 7/21 is greater than 2/7, 1/3 > 2/7.

Simplify the fraction 8/12.

• 4/6

• 5/7

• 2/3

• 3/4

Answer explanation

To simplify 8/12, divide both numerator and denominator by their greatest common factor, which is 4. This gives 2/3 as the simplified fraction.
