CHAPTER 1: FRACTIONS AND DECIMALS
1. Arrange the following decimals from largest to smallest: 1.5, 0.25,
1.025.
WORKING:
Compare the decimals by looking at the digits place by place.
1.5 has 1 in the units place and 5 in the tenths place.
1.025 has 1 in the units place, 0 in the tenths place, 2 in the hundredths
place.
0.25 has 0 in the units place.
Comparing tenths: 1.5 has 5 tenths, 1.025 has 0 tenths.
Therefore, 1.5 is largest, followed by 1.025, then 0.25.
ANSWER: 1.5, 1.025, 0.25
Pts: 1
Dif: Recall
Ref: Decimals
2. Arrange the following decimals from largest to smallest: 0.33, 0.045,
0.7.
,WORKING:
Compare the decimals by looking at the tenths place first.
0.7 has 7 tenths.
0.33 has 3 tenths.
0.045 has 0 tenths.
Therefore, 0.7 is largest, then 0.33, then 0.045.
ANSWER: 0.7, 0.33, 0.045
Pts: 1
Dif: Recall
Ref: Decimals
3. Arrange the following fractions from smallest to largest: 1/2, 3/4, 2/3.
WORKING:
Find a common denominator. The least common denominator for 2, 4,
and 3 is 12.
Convert each fraction:
1/2 = (1 × 6)/(2 × 6) = 6/12
3/4 = (3 × 3)/(4 × 3) = 9/12
2/3 = (2 × 4)/(3 × 4) = 8/12
Now compare numerators: 6, 8, 9.
Smallest to largest: 6/12, 8/12, 9/12 which corresponds to 1/2, 2/3, 3/4.
ANSWER: 1/2, 2/3, 3/4
Pts: 1
Dif: Application
Ref: Fractions
,4. Arrange the following fractions from smallest to largest: 5/6, 2/3, 1/2.
WORKING:
Find a common denominator. The least common denominator for 6, 3,
and 2 is 6.
Convert each fraction:
5/6 = 5/6
2/3 = (2 × 2)/(3 × 2) = 4/6
1/2 = (1 × 3)/(2 × 3) = 3/6
Now compare numerators: 3, 4, 5.
Smallest to largest: 3/6, 4/6, 5/6 which corresponds to 1/2, 2/3, 5/6.
ANSWER: 1/2, 2/3, 5/6
Pts: 1
Dif: Application

5. Reduce the fraction 24/36 to its lowest terms.
WORKING:
Find the greatest common divisor (GCD) of 24 and 36.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
The GCD is 12.
Divide both numerator and denominator by 12:
24 ÷ 12 = 2
36 ÷ 12 = 3
Therefore, 24/36 = 2/3
, ANSWER: 2/3
Pts: 1
Dif: Recall
Ref: Reducing Fractions
6. Reduce the fraction 18/24 to its lowest terms.
WORKING:
Find the greatest common divisor (GCD) of 18 and 24.
Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
The GCD is 6.
Divide both numerator and denominator by 6:
18 ÷ 6 = 3
24 ÷ 6 = 4
Therefore, 18/24 = 3/4
ANSWER: 3/4
Pts: 1
Dif: Recall
Ref: Reducing Fractions
7. Convert the improper fraction 17/5 to a mixed number.
WORKING:
Divide the numerator (17) by the denominator (5):
17 ÷ 5 = 3 with a remainder of 2
The quotient (3) becomes the whole number.
The remainder (2) becomes the numerator.
