Question

Mrs Lee had 3/10 of cake and Mrs chua had 1/4 of similar cake how much more did Mrs Lee have than mrs chua

Answer 1

To determine how much more cake Mrs. Lee had compared to Mrs. Chua, we need to subtract the amount of cake Mrs. Chua had from the amount of cake Mrs. Lee had.

Mrs. Lee had \( \frac{3}{10} \) of a cake, and Mrs. Chua had \( \frac{1}{4} \) of a cake.

Before subtracting, we need a common denominator for the fractions. The least common multiple of 10 and 4 is 20.

Now, convert both fractions to have a denominator of 20:

- For Mrs. Lee:
\[
\frac{3}{10} = \frac{3 \times 2}{10 \times 2} = \frac{6}{20}
\]

- For Mrs. Chua:
\[
\frac{1}{4} = \frac{1 \times 5}{4 \times 5} = \frac{5}{20}
\]

Now we can subtract Mrs. Chua's amount from Mrs. Lee's amount:

\[
\frac{6}{20} - \frac{5}{20} = \frac{6 - 5}{20} = \frac{1}{20}
\]

Thus, Mrs. Lee had \( \frac{1}{20} \) of a cake more than Mrs. Chua.
