Row one: 5/7 and 25/35 and 20/28 and 35/49 and 15/21 and 10/14
Row two: 21/33 and 28/44 and 7/11 and 14/22 and 49/77 and 35/55 and 42/66
...and etcetera! Just try to find the base fraction (simplest form) like 5/7 and 7/11 to help. :)
Bases in order: 5/7, 7/11, 1/6, 1/12, 1/3, 1/8, 1/4, 1/2 (lowest in this row is 5/10), 7/9, and 3/5
Take that base for each problem and take the numerator, the top number/part, or the denominator, the bottom number/whole (whichever is given), and divide it by that of the base then multiply the other part of the base to get that part of the other fraction. :)
