Question

Tính :

3/4 x 5/6 - 1/6 =

4/5 - 3/5 : 7/8 =

Answer 1

3/4 x 5/6 - 1/6 =5/8-1/6=11/24

4/5 - 3/5 : 7/8 =4/5-24/35=4/35

Answer 2

\(\dfrac{3}{4}\times\dfrac{5}{6}-\dfrac{1}{6}=\dfrac{5}{8}-\dfrac{1}{6}=\dfrac{15}{24}-\dfrac{4}{24}=\dfrac{9}{24}=\dfrac{3}{8}\)

\(\dfrac{4}{5}-\dfrac{3}{5}:\dfrac{7}{8}=\dfrac{4}{5}-\dfrac{24}{35}=\dfrac{28}{35}-\dfrac{24}{35}=\dfrac{4}{35}\)

`3/4 xx 5/6 - 1/6 = 5/8 - 1/6= 11/24`

`4/5 - 3/5 : 7/8 = 4/5 - 3/5 xx 8/7= 4/5 -24/35 = 4/35`

Answer 4

\(\dfrac{3}{4}\times\dfrac{5}{6}-\dfrac{1}{6}=\dfrac{15}{24}-\dfrac{1}{6}=\dfrac{15}{24}-\dfrac{4}{24}=\dfrac{11}{24}\)

\(\dfrac{4}{5}-\dfrac{3}{5}:\dfrac{7}{8}=\dfrac{4}{5}-\dfrac{3}{5}\times\dfrac{8}{7}=\dfrac{4}{5}-\dfrac{24}{35}=\dfrac{28}{35}-\dfrac{24}{35}=\dfrac{4}{35}\)

Answer 5

3/4 x 5/6 - 1/6 = =\(\dfrac{5}{8}-\dfrac{1}{6}=\dfrac{15}{24}-\dfrac{4}{24}=\dfrac{11}{24}\)

4/5 - 3/5 : 7/8 = \(\dfrac{4}{5}-\dfrac{3}{5}x\dfrac{8}{7}=\dfrac{4}{5}-\dfrac{24}{35}=\dfrac{28}{35}-\dfrac{24}{35}=\dfrac{4}{35}\)
