5/6 + 3/4

3/8 + 7/12

Answer 1

a: =5/7+1/6

=30/35+7/35

=37/35

b: =5/8+3/4

=5/8+6/8

=11/8

c: =10/12+9/12

=19/12

d: =9/24+14/24

=23/24

Answer 2

\(\dfrac{5}{7}+\dfrac{3}{18}=\dfrac{90}{126}+\dfrac{21}{126}=\dfrac{37}{42}\)

\(\dfrac{15}{24}+\dfrac{12}{16}=\dfrac{240}{384}+\dfrac{288}{384}=\dfrac{11}{8}\)

\(\dfrac{5}{6}+\dfrac{3}{4}=\dfrac{20}{24}+\dfrac{18}{24}=\dfrac{19}{12}\)

\(\dfrac{3}{8}+\dfrac{7}{12}=\dfrac{36}{96}+\dfrac{56}{96}=\dfrac{23}{24}\)

Answer 3

`5/7 + 3/18 = 90/126 + 21/126 = 111/126 = 37/42 `

 

`15/24 + 12/16 = 30/48 + 36/48 = 66/48 =11/8`

 

`5/6 + 3/4 = 10/12 + 9/12 = 19/2 `

 

`3/8 + 7/12 = 9/24 + 14/24 = 23/24`
