Here are the solutions for the fractions questions:
1. Write an equivalent fraction for each of the following:
- a) To find an equivalent fraction for 21, we can multiply the numerator and denominator by 2.
\frac{1}{2} = \frac{1 \times 2}{2 \times 2} = \frac{2{4}}
- b) To find an equivalent fraction for 62, we can simplify it by dividing the numerator and denominator by their greatest common divisor, which is 2.
\frac{2}{6} = \frac{2 \div 2}{6 \div 2} = \frac{1{3}}
- c) To find an equivalent fraction for 64, we can simplify it by dividing the numerator and denominator by their greatest common divisor, which is 2.
\frac{4}{6} = \frac{4 \div 2}{6 \div 2} = \frac{2{3}}
- d) To find an equivalent fraction for 31, we can multiply the numerator and denominator by 2.
\frac{1}{3} = \frac{1 \times 2}{3 \times 2} = \frac{2{6}}
- e) The fraction 22 represents a whole.
22=1
- f) To find an equivalent fraction for 63, we can simplify it by dividing the numerator and denominator by their greatest common divisor, which is 3.
\frac{3}{6} = \frac{3 \div 3}{6 \div 3} = \frac{1{2}}
- g) To find an equivalent fraction for 32, we can multiply the numerator and denominator by 2.
\frac{2}{3} = \frac{2 \times 2}{3 \times 2} = \frac{4{6}}
- h) The fraction 66 represents a whole.
66=1
- i) To find an equivalent fraction for 31, we can multiply the numerator and denominator by 2.
\frac{1}{3} = \frac{1 \times 2}{3 \times 2} = \frac{2{6}}
- j) To find an equivalent fraction for 32, we can multiply the numerator and denominator by 2.
\frac{2}{3} = \frac{2 \times 2}{3 \times 2} = \frac{4{6}}
- k) To find an equivalent fraction for 21, we can multiply the numerator and denominator by 2.
\frac{1}{2} = \frac{1 \times 2}{2 \times 2} = \frac{2{4}}
- l) To find an equivalent fraction for 65, we can multiply the numerator and denominator by 2.
\frac{5}{6} = \frac{5 \times 2}{6 \times 2} = \frac{10{12}}
2. Fill in <, > or =:
- a) Compare 21 and 31.
To compare, convert to a common denominator of 6: 21=63 and 31=62.
63>62⟹21>31
- b) Compare 21 and 61.
To compare, convert to a common denominator of 6: 21=63.
63>61⟹21>61
- c) Compare 31 and 63.
To compare, convert to a common denominator of 6: 31=62.
62<63⟹31<63
- d) Compare 21 and 32.
To compare, convert to a common denominator of 6: 21=63 and 32=64.
63<64⟹21<32
- e) Compare 32 and 61.
To compare, convert to a common denominator of 6: 32=64.
64>61⟹32>61
- f) Compare 65 and 32.
To compare, convert to a common denominator of 6: 32=64.
65>64⟹65>32
- g) Compare 32 and 66.
Simplify 66=1.
32<1⟹32<66
- h) Compare 31 and 64.
To compare, convert to a common denominator of 6: 31=62.
62<64⟹31<64
- i) Compare 61 and 62.
The denominators are already the same.
61<62⟹61<62
- j) Compare 21 and 33.
Simplify 33=1.
21<1⟹21<33
- k) Compare 21 and 61.
To compare, convert to a common denominator of 6: 21=63.
63>61⟹21>61
