Answer
Hey Prudence, good to see you again.
Here are the solutions to the problems:
1. Complete the fractions to make them equal.
a) (Given)
b) To get from to , we multiply by . So, we multiply the numerator by . \frac{3}{5} = \frac{3 \times 2}{5 \times 2} = \frac{6{10}}
c) To get from to , we multiply by . So, we multiply the numerator by . \frac{2}{6} = \frac{2 \times 2}{6 \times 2} = \frac{4{12}}
d) To get from to , we multiply by . So, we multiply the numerator by . \frac{6}{7} = \frac{6 \times 3}{7 \times 3} = \frac{18{21}}
e) To get from to , we divide by . So, we divide the numerator by . \frac{2}{4} = \frac{2 \div 2}{4 \div 2} = \frac{1{2}}
f) To get from to , we divide by . So, we divide the numerator by . \frac{9}{15} = \frac{9 \div 3}{15 \div 3} = \frac{3{5}}
g) To get from to , we multiply by . So, we multiply the numerator by . \frac{5}{6} = \frac{5 \times 3}{6 \times 3} = \frac{15{18}}
h) To get from to , we multiply by . So, we multiply the numerator by . \frac{7}{9} = \frac{7 \times 2}{9 \times 2} = \frac{14{18}}
i) To get from to , we divide by . So, we divide the numerator by . \frac{6}{22} = \frac{6 \div 2}{22 \div 2} = \frac{3{11}}
j) To get from to , we multiply by . So, we multiply the numerator by . \frac{20}{25} = \frac{20 \times 4}{25 \times 4} = \frac{80{100}}
2. What happens to the numerator and denominator? Extend the pattern down three more equivalent fractions.
In both cases, to find an equivalent fraction, both the numerator and the denominator are multiplied by the same non-zero number.
a) The pattern is to multiply both the numerator and denominator by each time. \frac{1}{3} = \frac{2}{6} = \frac{4}{12} = \frac{8}{24} = \frac{16{48}} = \frac{32{96}} = \frac{64{192}}
b) The pattern is to multiply both the numerator and denominator by each time. \frac{1}{5} = \frac{3}{15} = \frac{9}{45} = \frac{27}{135} = \frac{81{405}} = \frac{243{1215}} = \frac{729{3645}}
