Well first, you solve for C.
Step 1: Get C by itself.
C + 2/45 = 8/5
*Subtract "C" to both sides.
C + 2/45 = 8/5
-C -C
The problem now becomes 2/45 = 8/5c
Step 2: Divide 8/5 to both sides.
2/45 = 8/5c
-8/5
Step 3: Divide your fractions by doing reciprocal.
2/45 / 8/5
2/45 * 5/8
2 5
* = 10/360
45 8
10/360 can be simplified to 5/72
C = 5/72.
