15% of 2500 is 375—in cash terms, £375 from a £2500 base. Twenty-five hundred lines up neatly for the usual split: 10% is 250 (shift one place for “ten out of a hundred”), and 5% is half of that: 125. Add them and the fifteen-percent slice is a whole number again. You can also decompose the base as 1000 + 1500: 15% of 1000 is 150, 15% of 1500 is 225, and 150 + 225 = 375.

Formula used: (percentage ÷ 100) × number
Step 1: Take 10% of 2500: 250.
Step 2: Take 5% of 2500 by halving 250: 125.
Full formula: (15 ÷ 100) × 2500 = 375
Add the parts: 250 + 125 = 375. A “per hundred” check: there are 25 hundreds in 2500, and 15 × 25 = 375. For a larger round base on the same site, 15% of 5000 doubles both the total and the share to 750.
Ten percent of twenty-five hundred is 250—one clean decimal move. Five percent is half of that, 125, so fifteen percent is the sum of two integers you can keep in working memory. There is no trailing .5 in the answer here, unlike bases where halving ten percent leaves a half in the five-percent chunk.
For other rates on the same 2500, 20% of 2500 and 25% of 2500 show how the slice grows when you move past fifteen points; 40% of 2500 is a steeper share again for comparison.
