What's on this sheet

The questions are worded as comparisons rather than instructions: "40% less than 25" instead of "decrease 25 by 40%". That is how the idea actually arrives — a price cut, a smaller class, a shorter time — and it makes a child decide to subtract instead of following a verb. The arithmetic underneath is a percent-of followed by one subtraction; the reasoning is that the starting number is what the share comes off.

Why this sheet works

Every answer is a whole number, and that is a constraint on the pair rather than on either number alone. 40% of 25 is 10 and 40% of 26 is 10.4, so the sheet only draws numbers where the change lands whole — the same care the percent-of sheets take, so nothing here asks for a decimal a sixth-grader has not been set up to expect.

How this one works

One question from this sheet, worked through a step at a time.

25% less than 124

1%of124=1.24
1.24×25=31
12431=93
  1. Find one percent first — that is one hundredth of 124, which is 1.24.
  2. 25% is 25 of those, so multiply: 1.24 × 25 = 31.
  3. "Less than" means the 31 comes OFF the 124, and the 31 was never the answer: 124 − 31 = 93.
