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 - \(\frac{5}{6}\)= \(\frac{2}{1}\)- \(\frac{5}{6}\)= \(\frac{12}{6}\)+ \(\frac{5}{6}\)= \(\frac{12+5}{6}\)=\(\frac{17}{6}\)

a) 889972 + 96308 = 986280
b) \(\dfrac{5}{6}+\dfrac{7}{12}=\dfrac{10}{12}+\dfrac{7}{12}=\dfrac{17}{12}\)
c) \(3+\dfrac{5}{7}=\dfrac{21}{7}+\dfrac{5}{7}=\dfrac{26}{7}\)

1.
a) 889972 + 96306 = 986278
b) 726,83 - 349,67 = 377,16
c) \(\frac{7}{8}+\frac{3}{4}=\frac{13}{8}\)
d)\(2-\frac{5}{6}=\frac{7}{6}\)
889972+96308 =986380
2-5/6=7/6
7/8+3/4=2
726,83-349,67=375,16
