Question

2/3 - 5/8 =
11/10 - 2/5 : 2/3 =
7/12 + 1/4 x 2/3 =
 

Answer 1

`2/3-5/8=16/24-15/24=1/24`

`11/10-2/5:2/3=11/10-2/5xx3/2=11/10-3/5=11/10-6/10=5/10=1/2`

`7/12+1/4xx2/3=7/12+2/12=9/12=3/4`

Answer 2

\(\dfrac{2}{3}-\dfrac{5}{8}=\dfrac{16}{24}-\dfrac{15}{24}=\dfrac{1}{24}\)

 

\(\dfrac{11}{10}-\dfrac{2}{5}:\dfrac{2}{3}=\dfrac{11}{10}-\dfrac{2}{5}\times\dfrac{3}{2}=\dfrac{11}{10}-\dfrac{6}{10}=\dfrac{5}{10}=\dfrac{1}{2}\)

 

\(\dfrac{7}{12}+\dfrac{1}{4}\times\dfrac{2}{3}=\dfrac{7}{12}+\dfrac{2}{12}=\dfrac{9}{12}=\dfrac{3}{4}\)

Answer 3

2/3 - 5/8 = \(\dfrac{16}{24}-\dfrac{15}{24}=\dfrac{1}{24}\)
11/10 - 2/5 : 2/3 = \(\dfrac{11}{10}-\dfrac{2}{5}x\dfrac{3}{2}=\dfrac{11}{10}-\dfrac{3}{5}=\dfrac{11}{10}-\dfrac{6}{10}=\dfrac{5}{10}=\dfrac{1}{2}\)
7/12 + 1/4 x 2/3 = \(\dfrac{7}{12}+\dfrac{1}{6}=\dfrac{7}{12}+\dfrac{2}{12}=\dfrac{9}{12}=\dfrac{3}{4}\)

Answer 4

2/3 - 5/8 = 1/24
11/10 - 2/5 : 2/3 

= 11/10 - 3/5

= 1/2
7/12 + 1/4 x 2/3 

= 7/12 + 1/6

= 3/4

Answer 5

2/3 - 5/8 = 16/24 - 15/24 = 1/24
11/10 - 2/5 : 2/3 = 11/10 - ( 2/5 : 2/3 ) = 11/10 - ( 2/5 x 3/2 ) = 11/10 - 3/5 = 11/10 - 6/10 = 5/10 = 1/2
7/12 + 1/4 x 2/3 = 7/12 + ( 1/4 x 2/3 ) = 7/12 + 1/6 = 7/12 + 2/12 = 9/12 = 3/4
