To find 1/4 of 10, you simply need to divide 10 by 4. So you can do the following calculation:
10 ÷ 4 = 2.5
This means that 1/4 of 10 is 2.5.
To understand it better, think of 10 as a whole. When you divide it into four equal parts, each part is 2.5. Therefore, taking one of those parts gives you the answer.
