a)25/50 + 5/15 = 1/2 + 1/3 = 5/6
b)72/90 + 7/28 = 4/5 + 1/4 =\(1\frac{1}{20}\)
c)32/96 + 8/28 = 1/3 + 2/7 = 13/21
Chúc bạn tết vui vẻ nha!
a ) \(\frac{25}{50}+\frac{5}{15}=\frac{1}{2}+\frac{1}{3}=\frac{5}{6}\)
b ) \(\frac{72}{90}+\frac{7}{28}=\frac{4}{5}+\frac{1}{4}=\frac{21}{20}\)
c ) \(\frac{32}{96}+\frac{8}{28}=\frac{1}{3}+\frac{2}{7}=\frac{13}{21}\)
Chúc bạn học tốt !
