Question

1. answer The question


(12/5) - (3/10) = ? ​

Answer 1

=12/5-3/10

=(2×12-1×)/10

=(24-3)/10

=21/10

Answer 2

21/10

in 12/5& 3/10 both have different denominator so we should find two numbers LCM 5 and 10 after we get 5 × 2 = 10

so 5 × 2=10 & 21 ×2=24 = 24/10

3/10 can be multiply both sides with 1

so 24/10 - 3/10= 21/10
