Kenneth spent 1/4 of his weekly allowance on Monday. He spent 1/2 of the remainder on Tuesday. What fraction of his allowance was left for the rest of the week?
Let A be the weekly allowance
At the end of Monday he had spent A/4 and had 3A/4 left
On Tuesday he spent 3A/8 and since this was half of what he had at the start of Tuesday this must also have been what he had left for the rest of the week. i.e. He had 3/8 of his weekly allowance for the rest of the week.
