Question

subtract 2/13/36 and 1/5/9 with LCM​

Answer 1

Answer:

A - B = `8/7 - 3/4`

denominator of the two fraction is different. Therefore, find lcm for two denominators (7, 4) = 28

Multiply lcm with both numerator & denominator

`8/7 - 3/4 = (8\times28)/(7\times28) - (3\times28)/(4\times28)`

= `(8\times4)/(28) - (3\times7)/(28)`

= `(32)/(28) - (21)/(28)`

Subtract two numerator of the fraction

`(32)/(28) - (21)/(28) = (32 - 21)/28 = 11/28`

`8/7-3/4 = 11/28`
