Question

Arrange these numbers from least to greatest:
3/5,..5/7,..2/9

Answer 1

Make the denominator the same which would make it easier to compare the fractions.
Find the least common denominator of 5, 7 and 9 and multiply top and bottom of each fraction by the least common denominator. Then compare.

Answer 2

Or you can divide and express a couple of decimal places and then compare.

Answer 3

Hint:
\[\left\{\frac{3}{5},\frac{5}{7},\frac{2}{9}\right\}=\{0.6,0.714286,0.222222\} \]

Answer 4

Thanks

Answer 5

Wait I don't get it

Answer 6

\(\large \frac 35 = 0.6\)
\(\large \frac 57 \approx 0.7\)
\(\large \frac 29 \approx 0.2\)
Arrange 0.6, 0.7 and 0.2 from least to greatest.
Then you can arrange the corresponding fractions from least to greatest.
