Question

Tính:

a, 3/4 x (5/6 + 2/3)=

b, 3/2 - 2/3 : 2=

Answer 1

3/4 x 3/2 = 9/8

3/2 - 1/3 = 7/6

Answer 2

3/4x3/2=9/8

3/2-1/3=7/6

Answer 3

a, = 3/4 x 3/2 = 9/8

b, 3/2 - 1/3 = 7/6 

Answer 4

a) \(\dfrac{3}{4}\times\left(\dfrac{5}{6}+\dfrac{2}{3}\right)=\dfrac{3}{4}\times\left(\dfrac{10}{12}+\dfrac{8}{12}\right)=\dfrac{3}{4}\times\dfrac{18}{12}=\dfrac{3}{4}\times\dfrac{3}{4}=\dfrac{9}{8}\)

b) \(\dfrac{3}{2}-\dfrac{2}{3}\div2=\dfrac{3}{2}-\dfrac{1}{3}=\dfrac{9}{6}-\dfrac{2}{6}=\dfrac{7}{6}\)

Answer 5

= 9/8

= 7/6

Answer 6

3/4 x 3/2 = 9/8

3/2 - 1/3 = 7/6
