\(=\frac{-2}{4}+\frac{1}{4}\)
\(=\frac{-1}{4}\)
Lớp 5 mà học số nguyên âm hả bạn
\(-\frac{1}{2}+\frac{1}{4}\)
\(=-\left(\frac{1}{2}-\frac{1}{4}\right)\)
\(=-\left(\frac{2}{4}-\frac{1}{4}\right)\)
\(=-\frac{1}{4}\)
\(-\frac{1}{2}+\frac{1}{4}\)
\(=-\frac{2}{4}+\frac{1}{4}\)
\(=-\frac{1}{4}\)
\(\frac{-1}{2}+\frac{1}{4}\)
= \(\frac{-2}{4}+\frac{1}{4}\)
= \(\frac{\left(-2\right)+1}{4}\)
= \(\frac{-1}{4}\)
\(-\frac{1}{2}+\frac{1}{4}\)
= \(-\frac{2}{4}+\frac{1}{4}\)
= \(-\frac{1}{4}\)
\(\frac{-1}{2}+\frac{1}{4}\\ =\frac{-2}{4}+\frac{1}{4}\\ \frac{-1}{4}\)
