6.7 - 2.33 =

• 4.43

• 4.4

• 4.37

• 4.47

Answer explanation

To solve 6.7 - 2.33, align the decimal points: 6.70 - 2.33 = 4.37. Thus, the correct answer is 4.37.

• 8.5

Answer explanation

To convert \( \frac{35}{4} \) to a mixed number, divide 35 by 4. The quotient is 8 and the remainder is 3. Thus, it can be expressed as \( 8 \frac{3}{4} \), which matches the correct choice.

Convert 25\(\frac{1}{4}\) to an improper fraction.

• \(\frac{4}{101}\)

• \(\frac{101}{4}\)

• \(\frac{100}{25}\)

• \(\frac{25}{4}\)

Answer explanation

To convert 25\(\frac{1}{4}\) to an improper fraction, multiply the whole number 25 by the denominator 4, then add the numerator 1. This gives 25\(4\) + 1 = 101. Thus, the improper fraction is \(\frac{101}{4}\).

CCSS.4.NF.B.4

Answer explanation

To convert the mixed number 6\frac{4}{5} to an improper fraction, multiply the whole number (6) by the denominator (5) and add the numerator (4): 6 \times 5 + 4 = 30 + 4 = 34. Thus, it becomes \frac{34}{5}.

CCSS.4.NF.B.3

Answer explanation

To order the fractions, convert them to a common denominator (e.g., 8): \(\frac{1}{2} = \frac{4}{8}, \frac{1}{4} = \frac{2}{8}, \frac{3}{4} = \frac{6}{8}, \frac{5}{8} = \frac{5}{8}\). Thus, the order is \(\frac{3}{4}, \frac{1}{2}, \frac{5}{8}, \frac{1}{4}\).

Convert \(\frac{100}{3}\) to a mixed or whole number

• 33

• 33\(\frac{1}{3}\)

• 100\(\frac{1}{3}\)

• 33.5

Answer explanation

To convert \(\frac{100}{3}\) to a mixed number, divide 100 by 3, which gives 33 with a remainder of 1. This can be expressed as 33\(\frac{1}{3}\), making it the correct choice.

• 2

• 1

• 5

Answer explanation

To estimate 3 1/4 - 1 1/2, round 3 1/4 to 3 and 1 1/2 to 1. The calculation becomes 3 - 1 = 2. However, considering the fractions, the actual difference is closer to 1, making 1 the best estimate.

CCSS.5.NF.A.2

Answer explanation

To find equivalent fractions with a common denominator, convert \( \frac{3}{5} \) to \( \frac{30}{50} \) and \( \frac{7}{10} \) to \( \frac{35}{50} \). Both fractions share the denominator 50, making \( \frac{30}{50} \) and \( \frac{35}{50} \) correct.

A number is divisible by 2 if...

• it ends in 0, 2, 4, 6, or 8

• it is uneven

Answer explanation

A number is divisible by 2 if it ends in 0, 2, 4, 6, or 8. This is because these digits are even, while an uneven number would end in 1, 3, 5, 7, or 9, making it not divisible by 2.
