Question

find which rational number is greater a)5/-7,-11/7 b)-10/3,11/-5​

Answer 1

Answer:

a) 5/-7 = -5/7 & -11/7

so -5/7 is greater

b) -10/3 & 11/-5 = -11/5

so , lcm of 5 and 3 = 15

convert into like fractions by the lcm

= -10 * 5 / 3 * 5 = -50/15 ; as lcm / denominator = 15/3 = 5

= -11 * 3 / 5 * 3 = -33/ 15 ; as lcm/ denominator = 15/5 = 3

so -10/3 = -50/15

and -11/5 = -33/15

-33/15 is greater than -50/15

since -11/5 is greater than -10/3

hence proved
