Question

5/6 + 7/12

9/16 - 3/8 

11/10 + 3/5 : 2/3

Answer 1

5/6 + 7/12 = 10/12 + 7/12 = 17/12

9/16 - 3/8 = 9/16 - 6/16 = 3/16

11/10 + 3/5 : 2/3 =11/10 + 3/5 x 3/2 = 11/10 + 9/10 = 20/10 = 2

Answer 2

\(\dfrac{5}{6}+\dfrac{7}{12}=\dfrac{10}{12}+\dfrac{7}{12}=\dfrac{17}{12}\)

\(\dfrac{9}{16}-\dfrac{3}{8}=\dfrac{9}{16}-\dfrac{6}{16}=\dfrac{3}{16}\)

\(\dfrac{11}{10}+\dfrac{3}{5}:\dfrac{2}{3}=\dfrac{11}{10}+\dfrac{3}{5}\times\dfrac{3}{2}=\dfrac{11}{10}+\dfrac{9}{10}=\dfrac{20}{10}=2\)

Answer 3

5/6 + 7/12

= 10/12 + 7/12

= 17/12 

9/16 - 3/8

= 9/16 - 6/16

= 3/16 

11/10 + 3/5 : 2/3

= 11/10 + ( 3/5 : 2/3 )

= 11/10 + ( 3/5 x 3/2 )

= 11/10 + 9/10

= 20/10 = 2.

Answer 4

5/6 + 7/12 = 10/12 + 7/12 = 17/12

9/16 - 3/8 = 9/16 - 6/16 = 3/16

11/10 + 3/5 : 2/3 =11/10 + 3/5 x 3/2 = 11/10 + 9/10 = 20/10 = 2
