A movie and popcorn at the STAR Cineplex costs $13.65. This is $6.35 less than 1/3 of Katy's weekly babysitting earnings.

Multiply ⅓ by $13.65 and subtract $6.35
⅓x=$13.65-$6.35
⅓x=$13.65-$6.35

Maybe something like this.
20.00=(1/3)(k)
13.65 plus 6.35 would equal twenty, seen on the left. K would equal Kate's earnings. To figure out what her income is, divide by 1/3. For lack of being able to explain it via keyboard, it will look like: 20 over 1 equals 1 over 3. Inverse the second fraction so now it's: 20 over 1 equals 3 over 1. Just multiply across, and your answer will be 60, this is Kate's weekly earnings. Hope this helps :)
Edit: Sorry, explained it wrong. It will look like: 20 over 1 divided by 1 over 3. Then, when you invert it, it will look like: 20 over 1 multiplied by 3 over 1, at which point you will multiply to get 60. Hope this helps more :)

Let x = Katy's weekly babysitting earnings.
(1/3)x = 13.65
(1/3)x = 13.65

13.65 = Weekly earning * 1/3 - 6.35
13.65 + 6.35 = Weekly earning * 1/3
3(13.65 + 6.35) = weekly earning
Weekly earnings = 3*(13.65 + 6.35)
= 60
13.65 + 6.35 = Weekly earning * 1/3
3(13.65 + 6.35) = weekly earning
Weekly earnings = 3*(13.65 + 6.35)
= 60
