Question

\(\dfrac{4}{2}\):\(\dfrac{3}{11}\)             \(\dfrac{3}{5}\)+\(\dfrac{2}{7}\)            \(\dfrac{2}{3}\)*\(\dfrac{3}{5}\)          \(\dfrac{7}{4}\)-\(\dfrac{3}{2}\)

Answer 1

\(a,=\dfrac{22}{3}\\ b,=\dfrac{3.7+2.5}{35}=\dfrac{31}{35}\\ c,=\dfrac{2}{5}\\ d,=\dfrac{7-6}{4}=\dfrac{1}{4}\)

Answer 2

`4/2 : 3/11=4/2 xx 11/3=44/6=22/3`

`3/5 + 2/7=21/35 + 10/35=31/35`

`2/3 xx3/5=6/15=2/5`

`7/4-3/2=7/4-6/4=1/4`

Answer 3

44/6

31/35

6/15 

1/4

 

Answer 4

\(\dfrac{4}{2}:\dfrac{3}{11}=\dfrac{4}{2}\times\dfrac{11}{3}=\dfrac{44}{6}=\dfrac{22}{3}\\ \dfrac{3}{5}+\dfrac{2}{7}=\dfrac{21}{35}+\dfrac{10}{35}=\dfrac{31}{35}\\ \dfrac{2}{3}\times\dfrac{3}{5}=\dfrac{2\times3}{3\times5}=\dfrac{6}{15}=\dfrac{2}{5}\\ \dfrac{7}{4}-\dfrac{3}{2}=\dfrac{7}{4}-\dfrac{6}{4}=\dfrac{1}{4}\)
