Question

310 + 1/5
6/7 - 1/2
2/5 x 1/4 : 3/2

Answer 1

\(310+\dfrac{1}{5}=\dfrac{1550}{5}+\dfrac{1}{5}=\dfrac{1551}{5}\)

\(\dfrac{6}{7}-\dfrac{1}{2}=\dfrac{12}{14}-\dfrac{7}{14}=\dfrac{5}{14}\)

\(\dfrac{2}{5}\times\dfrac{1}{4}\times\dfrac{2}{3}=\dfrac{4}{60}=\dfrac{1}{15}\)

Answer 2

\(310+\dfrac{1}{5}=\dfrac{1550}{5}+\dfrac{1}{5}=\dfrac{1551}{5}\)

\(\dfrac{6}{7}-\dfrac{1}{2}=\dfrac{12}{14}-\dfrac{7}{14}=\dfrac{5}{14}\)

\(\dfrac{2}{5}\times\dfrac{1}{4}:\dfrac{3}{2}=\dfrac{1}{10}:\dfrac{3}{2}=\dfrac{1}{10}\times\dfrac{2}{3}=\dfrac{1}{15}\)

Answer 3
