Which number sentence is true?

• 2/4 > 2/6

• 3/6 < 3/9

• 4/8 > 4/6

• 5/6 < 5/10

Answer explanation

To compare the fractions, convert them to a common denominator or decimal. 2/4 equals 0.5 and 2/6 equals approximately 0.33, so 2/4 > 2/6 is true. The other options are false when evaluated.

Which choice is greater than 2/5 and less than 2/3?

• 2/4

• 2/6

• 2/7

• 2/8

Answer explanation

To find a fraction greater than 2/5 (0.4) and less than 2/3 (0.6667), we compare the options. 2/4 (0.5) fits this range, while 2/6 (0.3333), 2/7 (0.2857), and 2/8 (0.25) do not.

Which statement is true?

• 1/2 > 1/3

• 1/2 < 1/3

• 1/3 < 1/4

• 1/3 > 1/2

Answer explanation

To compare fractions, we can find a common denominator or convert them to decimals. 1/2 equals 0.5 and 1/3 equals approximately 0.333. Since 0.5 is greater than 0.333, the statement 1/2 > 1/3 is true.

Which compares the shaded parts of the fractions below?

• 2/1 > 1/2

• 2/2 > 1/2

• 2/2 = 1/2

• 2/2 < 1/2

Answer explanation

To compare the fractions, convert them to a common denominator or evaluate their values. 2/1 equals 2, while 1/2 equals 0.5. Thus, 2/1 > 1/2 is correct.

Rachel and Tameka shared the pie shown.

Rachel ate 3/6 of the pie. Tameka ate less. How much of the pie did Tameka eat?

• 4/6

• 2/6

• 6/6

• 5/6
