Question

use LCM method and fill in the boxes with greater than, smaller than or = 5/12 4/9 which is greater

Answer 1

5/12 = 4/9
4*9 = 12*4

36 < 48
so
5/12 < 4/9

Answer 2

LCM of 9 and 12 is 36 .
Therefore we can write-:
5/12=5×3/12×3=15/36
and 4/9=4×4/9×4=16/36
clearly 16 is greater than 15 therefore 16/36>15/36=>4/9>5/12
