Question

Solve the unknown viable

7c/12 + 5c/16=15/48 +c

Answer 1

deconstructing
48 : 2 = 24
24 : 2 = 12
12 :2 = 6
6 : 2 = 3
3 : 3 = 1
2 * 2 * 2 * 2 * 3 = 48
...................................
16 : 2 = 8
8 : 2 = 4
4 : 2 = 2
2 : 2 = 1
2 * 2* 2 * 2 = 16
..................................
12 : 2 = 6
`(7c)/(12) + (5c)/(16) = (15)/(48) + c \\ \\ (7c*4)/(12*4) + (5c*3)/(16*3) - (15)/(48) = c \\ \\ (28c + 15c)/(48) - (15)/(48) = c \\ \\ 48c = 43c - 15 \\ \\ 48c - 43c = -15 \\ \\ 5c =- 15 \\ \\ c = -3`
6 : 2 = 3
3 : 3 = 1
common denominator 48
