Answer 4

sẽ khá là dài:

5/6 x 3/7 + 1/2

= 5/14 + 1/2

= 5/14 + 7/14

= 12/14 = 6/7

1/3 : 1/5 - 1

= 1/3 x 5 - 1

= 5/3 - 3/3

= 2/3

4/3 - 1/2 : 3/2

= 4/3 - 1/2 x 2/3

= 4/3 - 1/3

= 3/3 = 1

Answer 5

a.\(\dfrac{5}{14}\) + \(\dfrac{1}{2}\) = \(\dfrac{6}{7}\)

b.\(\dfrac{5}{3}\) - 1 = \(\dfrac{2}{3}\)

c.\(\dfrac{4}{3}-\dfrac{1}{3}\)=1
