13/15 − 4/6 = 18/90 which reduces to 1/5
-13
13
The LCM of 10 and 13 is 130 9/10 (13) + 6/13 (10) 117/130 + 60/130 = 177/130 = 1 and 47/130
You first multiply 6 by 13 giving you 78. Then subtract 9 giving you 69. Then subtract 6*6 which is 36 giving you 33. Then you subtract 9 to get 24.
It means to take 6 away from something. 10 subtract 6 is 4.
(5/6) / (13/12) = (5/6) x (12/13) = (5/1) x (2/13) = 10/13
The number is 16 minus 10 = 6
6 13/15 + 4 1/15 = 10 + 13/15+1/15 = 10 14/15

You subtract as with base ten, except that instead of "borrowing" 10 from the column on the left, you borrow 8.So assume all number below are in base 8.3 5- 1 6--------You cannot subtract 6 from 5 so you need to borrow.2313- 1 6--------where the 13 is the borrowed 8 plus the 5 that was already there..13-6 = 7and 2-1 = 1so the answer is 17.You subtract as with base ten, except that instead of "borrowing" 10 from the column on the left, you borrow 8.So assume all number below are in base 8.3 5- 1 6--------You cannot subtract 6 from 5 so you need to borrow.2313- 1 6--------where the 13 is the borrowed 8 plus the 5 that was already there..13-6 = 7and 2-1 = 1so the answer is 17.You subtract as with base ten, except that instead of "borrowing" 10 from the column on the left, you borrow 8.So assume all number below are in base 8.3 5- 1 6--------You cannot subtract 6 from 5 so you need to borrow.2313- 1 6--------where the 13 is the borrowed 8 plus the 5 that was already there..13-6 = 7and 2-1 = 1so the answer is 17.You subtract as with base ten, except that instead of "borrowing" 10 from the column on the left, you borrow 8.So assume all number below are in base 8.3 5- 1 6--------You cannot subtract 6 from 5 so you need to borrow.2313- 1 6--------where the 13 is the borrowed 8 plus the 5 that was already there..13-6 = 7and 2-1 = 1so the answer is 17.
