Răspuns:

Explicație pas cu pas:

7/30-3/20=14/60-9/60=5/60=1/12

8/15-9/20=160/300-135/300=25/300=1/12

8/21-4/35=280/735-84/735=196/735

7/6-3/4-1/12=14/12-9/12-1/12=5/12-1/12=4/12=1/3

Answer 2

$\it e)\ \ \dfrac{^{2)}7}{30}-\dfrac{^{3)}3}{20}=\dfrac{14-9}{60}=\dfrac{5^{(5}}{60}=\dfrac{1}{12}\\ \\ \\ f)\ \ \dfrac{^{4)}8}{15}-\dfrac{^{3)}9}{20}=\dfrac{32-27}{60}=\dfrac{5^{(5}}{60}=\dfrac{1}{12}\\ \\ \\ g)\ \ \dfrac{^{5)}8}{21}-\dfrac{^{3)}4}{35}=\dfrac{40-12}{105}=\dfrac{28^{(7}}{105}=\dfrac{4}{15}$

$\it h)\ \ \dfrac{^{2)}7}{6}-\dfrac{^{3)}3}{4}-\dfrac{1}{12}=\dfrac{14-9-1}{12}=\dfrac{4^{(4}}{12}=\dfrac{1}{3}$
