Question

Find the difference 2\15-1\20​

Answer 1

Answer:

2/15-1/20

=LCM of 15 and 20 is 60

so,

2/15*4/4=8/60

1/20*3/3=3/60

therefore, difference b/w 8/60 and3/60

=8/60-3/60

=8-3/60

=5/60

=12

Answer 2

Explanation:

firstly We have to do LCM.

so LCM of 15 and 20 = 60

then subtract = 2/15 - 1/20 so same the LCM

first we have to find that 15 table take 60?

yes 15×4 = 60. so we have to multiply 4 with 2 because denominator take 4 same thing with numerator have to take 4 so 2×4 =8

and second we also take Same thing.

so denominator is 20×3=60 and numerator is 1×3=3 so ans- 8 - 3 / 60 = 5/60 and cut with 5 so 1/12..
