Answer (2)
Too many points for such a simple explanation :)) Whatever: To get 1/4 of a number you multiply the number by 1/4. Same for any non-percent number. If the number is a percent, say, 23,5%, you first divide it by 100 to get a non-percent, then do the same, that is, multiply it by the number. Our result is 4 1 ∗ 10 = 4 10 = 2 5 = 2 2 1 = 2.5
To find \(\frac{1}{4}\) of 10, multiply 10 by \(\frac{1}{4}\), resulting in \(\frac{10}{4} = 2.5\). Thus, \(\frac{1}{4}\) of 10 is 2.5.
