Question

a, 9/6 - 4/12 x 7/8

b, 1/5 : 6 + 1/5

Answer 1

a) \(\dfrac{9}{6}-\dfrac{4}{12}x\dfrac{7}{8}\)

\(=\dfrac{3}{2}-\dfrac{1}{3}x\dfrac{7}{8}\)

\(=\dfrac{3}{2}-\dfrac{7}{24}\)

\(=\dfrac{36}{24}-\dfrac{7}{24}\)

\(=\dfrac{29}{24}\)

b) \(\dfrac{1}{5}:6+\dfrac{1}{5}\)

\(=\dfrac{1}{5}x\dfrac{1}{6}+\dfrac{1}{5}\)

\(=\dfrac{1}{30}+\dfrac{1}{5}\)

\(=\dfrac{1}{30}+\dfrac{6}{30}=\dfrac{7}{30}\)

Answer 2

a=29/4
b=7/30

Answer 3

a) 9/6 - 4/12 × 7/8

= 3/2 - 7/24

= 36/24 - 7/24

= 29/24

b) 1/5 : 6 + 1/5

= 1/30 + 1/5

= 1/30 + 6/30

= 7/30

Answer 4

a=29/4
b=7/30
