To find 1 by 4 of 1 by 2, we need to multiply the two fractions together. The calculation can be broken down as follows:
1 by 4 can be written as the fraction 1/4, and 1 by 2 can be written as 1/2. When multiplying fractions, we multiply the numerators together and the denominators together:
(1 × 1) / (4 × 2) = 1 / 8
So, 1 by 4 of 1 by 2 is equal to 1/8. This means if you have a whole and divide it into 8 equal parts, one of those parts represents 1 by 4 of 1 by 2.
