Question

write two equivalent rational numbers for each of the following:
a) 6 upon -7
b) -2 upon 5
c) 1 upon 20
d) -4 upon -8

Answer 1

Answer:

$a) \frac{6}{ - 7} \\ equivalent \: ratios = \frac{12}{ - 14} and \frac{18}{ - 21}$

$b) \frac{ - 2}{5} \\ equivalent \: ratios = \frac{ - 4}{10} and \: \frac{ - 6}{15}$

$c) \frac{1}{20} \\ equivalent \: ratios = \frac{2}{40} and \frac{3}{60}$

$\frac{ - 4}{ - 8} \\ equivalent \: ratios = \frac{ - 2}{ - 4} and \frac{ - 8}{ - 16} \\ negatives \: can \: be \: cancelled$

Answer 2

Equivalent rational numbers are rational numbers that have the same value but which are represented in a different form.
