5/12 + 3/4 - 1/3 = 7/6 - 1/3 = 1/2
1/4 - 3/7 + 11/14 = -5/28 + 11/14 = 17/28
a) \(\frac{5}{12}+\frac{3}{4}-\frac{1}{3}=\frac{5}{12}+\frac{9}{12}-\frac{4}{12}=\frac{5+9-4}{12}=\frac{10}{12}=\frac{5}{6}\)
b) \(\frac{1}{4}-\frac{3}{7}+\frac{11}{14}=\frac{7}{28}-\frac{12}{28}+\frac{22}{28}=\frac{7-12+22}{28}=\frac{17}{28}\)
5/12+3/4-1/3=5/6
1/4-3/7+11/14=17/28
\(\frac{5}{12}\)+ \(\frac{3}{4}\)- \(\frac{1}{3}\)
= \(\frac{5}{12}\)+ \(\frac{9}{12}\)- \(\frac{4}{12}\)
= \(\frac{5+9-4}{12}\)
= \(\frac{10}{12}\)= \(\frac{5}{6}\)
\(\frac{1}{4}\)- \(\frac{3}{7}\)+ \(\frac{11}{14}\)
= \(\frac{7}{28}\) - \(\frac{12}{28}\)+ \(\frac{22}{28}\)
= \(\frac{7}{28}\)+ \(\frac{22}{28}\)- \(\frac{12}{28}\)
= \(\frac{7+22-12}{28}\)
= \(\frac{17}{28}\)
