Question

write the following in order of size 1/3,2/9,1/4,3/16,3/10

Answer 1

9=3², 16=4², 10=2×5.

3×3×4×4×5=720 is divisible by 3, 9, 16, 10 and 4.

Multiply each fraction by 720 to find the numerator, then divide by 720 to work out the equivalent fraction.

240/720, 160/720, 180/720, 135/720, 216/720.

The order of the numerators is the order of the original fractions.

135/720=3/16, 160/720=2/9, 180/720=1/4, 216/720=3/10, 240/720=1/3.

3/16, 2/9, 1/4, 3/10, 1/3.
