Now 108 is taken as the common denominator.
The number with which we have to multiply each
denominator to get 108 is taken and that number
multiplies each numerator as shown below.
= ( 8 x 12 - 5 x 9 - 13 x 4 + 5 x 18)⁄108
= (96 - 45 - 52 + 90)⁄108 = 89⁄108.

Progressive Learning of Math : Subtracting Fractions
Recently, I have found a series of math curricula (Both Hard Copy and Digital Copy) developed by a Lady Teacher who taught everyone from Pre-K students to doctoral students and who is a Ph.D. in Mathematics Education.
This series is very different and advantageous over many of the traditional books available. These give students tools that other books do not. Other books just give practice. These teach students “tricks” and new ways to think.
These build a student’s new knowledge of concepts from their existing knowledge. These provide many pages of practice that gradually increases in difficulty and provide constant review.
