C+2/45=8/5
how do u find what c is

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.
