Helen found ⅔ of a bibingka on a plate and ate ½ of it. What part of the bibingka is left?

\begin{gathered} \\ \sf{} = \frac{2}{3} - \frac{1}{2} \\ \\ \sf{} = \frac{2\times 2}{3 \times 2} - \frac{1 \times 3}{2 \times 3} \\ \\ \sf{} = \frac{4}{6} - \frac{3}{6} \\ \\ \sf{} = \frac{4-3}{6} \\ \\ \huge\boxed{\sf{} = \frac{1}{6} } \\ \\ \\ \end{gathered}

Juan bought a 3-meter cloth for a project. He used 1 ¼m for pants. How many meters of cloth was left?

\begin{gathered}\\ \sf{} = 3 - 1 \frac{1}{4} \\ \\ \sf{} = 3 - \frac{1 \times 4 + 1}{4} \\ \\ \sf{} = 3 - \frac{5}{4} \\ \\ \sf{} = 3 \times \frac{4}{4} - \frac{5}{4} \\ \\ \sf{} = \frac{1}{4} - \frac{5}{4} \\ \\ \sf{} = \frac{12 - 5}{4} \\ \\ \sf{} = \frac{7}{4} \\ \\ \huge\boxed{\sf{} = 1 \frac{3}{4} } \\ \\ \\ \\ \end{gathered}
