Which fraction would be the result of reducing 6/10 to its lowest terms?
Record the answer as a fraction. __
- Correct Answer - 3/5
Rationale: Step 1: 6÷2=3
Step 2: 10÷2=5
Which is the lowest common denominator of the fractions 6/10 and 2/5?
Record the answer using a whole number. __
- Correct Answer - 5
Rationale: Both denominators, 10 and 5, can be evenly divided by 5. So,
5 is the lowest common denominator.
Calculate the sum of: 3/10 + 2/10
- Correct Answer - 1/2
Rationale: The first step is to add the numerators: 3 + 2/10
The next step is to place the sum over the common denominator and
reduce to lowest terms: 5/10 = 1/2
,Calculate the sum of: 2/3 + 1/4
- Correct Answer - 11/12
Rationale: The first step is to multiply denominators to find the lowest
common denominator. 3 × 4 = 12
The second step is to change each fraction to an equivalent fraction with
12 as the denominator. 2/3 = 8/12 and 1/4 = 3/12 The third step is to
place the sum over the lowest common denominator. 8 + 3/12 = 11/12
Calculate the sum of: 2 1/2 + 5 2/5
- Correct Answer - 7 9/10
Rationale: Step 1: Multiply denominators to find the lowest common
denominator. 2 × 5 = 10
Step 2: Change each fraction to an equivalent fraction with 10 as the
denominator. 1/2 = 5/10 and 2/5 = 4/10
Step 3: Place the sum of the numerators over the lowest common
denominator and write the fraction next to the sum of the whole
numbers. 2 5/10 + 5 4/10 = 7 9/10
Calculate the difference of: 9/8 - 7/8
- Correct Answer - 1/4
Rationale: Step 1: Place the numerator of the subtrahend (the number
being subtracted) from that of the minuend (the number from which it is
subtracted). 9−7/8
, Step 2: Next place the difference over the common denominator and
reduce to the lowest terms. 2/8 = 1/4 (reduced to lowest terms)
Calculate the difference of: 4/15 - 2/45
- Correct Answer - 2/9
Rationale: Change each fraction to its equivalent with 45 as the lowest
common denominator.
Step 1: 4/15 = 12/45
Step 2: 12/45 - 2/45
Step 3: 12 - 2/45 = 10/45
Step 4: 10/45 = 2/9 (reduced to lowest terms)
Calculate the difference of : 14 3/16 - 5 1/8
- Correct Answer - 9 1/16
Rationale: Determine the lowest common denominator, which is 16.
Change each fraction to its equivalent with 16 as the denominator.
Step 1: 1/8 = 2/16
Step 2: 14 3/16 - 5 2/16
Step 3: 14 3/16 - 5 2/16 = 9 1/16
Calculate the product of: 5/4 × 4/10
- Correct Answer - 1/2
