6 9/16k=31 13/32

The easiest way to solve this is to convert these fractions into improper fractions.

6 9/16 = 105/16
31 13/32 = 1005/32

105/16k = 1005/32

Solve for k.

• math - Ms. Sue, Tuesday, July 17, 2012 at 9:31pm

k = (1005/32) / (105/16)

k = (1005/32) * (16/105)

k = 16080 / 3360

k = 4.7857

I know this is a lot of numbers. However, we can estimate the answer to check it.

31/7 = 4.4

That's close -- so k must equal 4.7857
