43×43−41=
\( \frac{3}{4}\times\frac{3}{4}-\frac{1}{4}= \)
\( \frac{1}{2}\times\frac{1}{2}+\frac{3}{4}= \)
\( \frac{3}{5}\times\frac{2}{3}+\frac{2}{5}= \)
\( \frac{2}{3}\times\frac{1}{3}+\frac{2}{9}= \)
\( \frac{3}{4}\times\frac{1}{2}+\frac{5}{8}= \)
\( \frac{4}{4}\times\frac{1}{2}+\frac{3}{8}= \)
\( \frac{2}{3}\times\frac{2}{3}+\frac{4}{9}= \)
\( \frac{1}{4}\times\frac{1}{2}+\frac{3}{8}= \)
\( \frac{1}{4}\times\frac{4}{5}+\frac{11}{20}= \)
\( \frac{4}{5}\times\frac{1}{2}+\frac{3}{10}= \)
Resuelve lo siguiente:
\( \frac{3}{5}\times\frac{1}{2}+\frac{3}{10}= \)
\( \frac{1}{4}\times(\frac{1}{3}+\frac{1}{2})= \)
Resuelve lo siguiente:
