I figured it out by figuring out what the percent is as a fractions, by the cost and dividing by the fractions denominator. Then misusing the total from the cost.

The thing I found most challenging was using the multiplication and division strategies to estimate and solve problems with fractions, because it was pretty hard to find a strategy that worked. 

Here were the strategies we did: 

- Use multiplication and division strategies we used to estimate and solve problems with fractions, e.g.
>12 ÷ 3 = 1 2/3 
> Find a fraction of another fraction by multiplying.
>Describe and show remaining tenths, hundredths, thousandths as decimal fractions and relate them to place value order.

>- Work out and explain percentages of simple amounts
