Question

a,\(\dfrac{2}{9}+\dfrac{1}{6}\)

 

b,\(\dfrac{5}{6}-\dfrac{4}{7}\)

 

c,\(\dfrac{3}{8}\)x\(\dfrac{6}{15}\)

 

d,\(\dfrac{7}{12}:\dfrac{4}{7}\)

 

e,\(\dfrac{4}{7}:3\)

 

 

Answer 1

a,2/9+1/6=7/18

b,5/6-4/7=11/42

c,3/8.6/15=3/20

d,7/12:4/7=49/48

e,4/7:3=4/21

Answer 2

a, 7/18

b,11/42

c,3/20

d,49/48

e, 4/21

Answer 3

a: 2/9+1/6=4/18+3/18=7/18

b: 5/6-4/7=35/42-24/42=11/42

c: 3/8x6/15=18/120=3/20

Answer 4

a \(\dfrac{2}{9}+\dfrac{1}{6}=\dfrac{4}{18}+\dfrac{3}{18}=\dfrac{7}{18}\)

b \(\dfrac{5}{6}-\dfrac{4}{7}=\dfrac{35}{42}-\dfrac{24}{42}=\dfrac{11}{42}\)

c \(\dfrac{3}{8}\times\dfrac{6}{15}=\dfrac{1}{4}\times\dfrac{3}{5}=\dfrac{3}{20}\)

d \(\dfrac{7}{12}:\dfrac{4}{7}=\dfrac{7}{12}\times\dfrac{7}{4}=\dfrac{49}{48}\)

e \(\dfrac{4}{7}:3=\dfrac{4}{7}\times\dfrac{1}{3}=\dfrac{4}{21}\)

Answer 5

\(a,\) \(\dfrac{2}{9}+\dfrac{1}{6}=\dfrac{4}{18}+\dfrac{3}{18}=\dfrac{7}{18}\) 

\(b,\) \(\dfrac{5}{6}-\dfrac{4}{7}=\dfrac{35}{42}-\dfrac{24}{42}=\dfrac{11}{42}\) 

\(c,\) \(\dfrac{3}{8}\times\dfrac{6}{15}=\dfrac{18}{120}=\dfrac{3}{20}\) 

\(d,\) \(\dfrac{7}{12}:\dfrac{4}{7}=\dfrac{7}{12}\times\dfrac{7}{4}=\dfrac{49}{48}\) 

\(e,\) \(\dfrac{4}{7}:3=\dfrac{4}{7}\times\dfrac{1}{3}=\dfrac{4}{21}\)
