Bài tập 4 trang 60 toán lớp 4 tập 2 Cánh diều:Tính (theo mẫu)a) $1-\frac{1}{2}$b)...

Đáp án:
a) $1-\frac{1}{2} = \frac{2}{2} - \frac{1}{2} = \frac{1}{2}$
b) $5-\frac{7}{3} = \frac{15}{3} - \frac{7}{3} = \frac{8}{3}$
c) $\frac{11}{2} - 3 = \frac{11}{2} - \frac{6}{2} = \frac{5}{2}$

a) $1-\frac{1}{2} = \frac{2}{2} - \frac{1}{2} = \frac{1}{2}$
b) $5-\frac{7}{3} = \frac{15}{3} - \frac{7}{3} = \frac{8}{3}$
c) $\frac{11}{2} - 3 = \frac{11}{2} - \frac{6}{2} = \frac{5}{2}$

a) $1-\frac{1}{2} = \frac{2}{2} - \frac{1}{2} = \frac{1}{2}$
b) $5-\frac{7}{3} = \frac{15}{3} - \frac{7}{3} = \frac{8}{3}$
c) $\frac{11}{2} - 3 = \frac{11}{2} - \frac{6}{2} = \frac{5}{2}$

c) Tính $\frac{11}{2} - 3 = \frac{11}{2} - \frac{6}{2} = \frac{5}{2}$

b) Tính $5-\frac{7}{3} = \frac{15}{3} - \frac{7}{3} = \frac{8}{3}$
