a)889972 + 96308 = 986280
b ) \(\frac{7}{8}\)+ \(\frac{3}{4}\)= \(\frac{7}{8}\)+ \(\frac{6}{8}\)= \(\frac{7+6}{8}\)=\(\frac{13}{8}\)
c)2 - \(\frac{5}{6}\)= \(\frac{2}{1}\)- \(\frac{5}{6}\)= \(\frac{12}{6}\)+ \(\frac{5}{6}\)= \(\frac{12+5}{6}\)=\(\frac{17}{6}\)
d ) 726,83 - 349,67 = 377,16
Chúc bạn học tốt nha
