Question

12/25+ 21/25

80/99+2/99

7/5+5/7

 

Answer 1

`12/25+ 21/25`

`= ( 12+21)/25`

`= 33/25`

__

`80/99+2/99`

`=(80+2)/99`

`=82/99`

__

`7/5+5/7`

`=49/35+25/35`

`=(49+25)/35`

`=74/35`

Answer 2

`12/25+ 21/25=(12+21)/25=33/25`

`80/99+2/99=(80+2)/99=82/99`

`7/5+5/7=49/35+25/35=(49+25)/35=74/35`

Answer 3

\(\dfrac{12}{25}+\dfrac{21}{25}=\dfrac{12+21}{25}=\dfrac{33}{25}\\ \dfrac{80}{99}+\dfrac{2}{99}=\dfrac{80+2}{99}=\dfrac{82}{99}\\ \dfrac{7}{5}+\dfrac{5}{7}=\dfrac{49}{35}+\dfrac{25}{35}=\dfrac{49+25}{35}=\dfrac{74}{35}\)

Answer 4

\(\dfrac{12}{25}+\dfrac{21}{25}\)

\(=\dfrac{12+21}{25}\)

\(=\dfrac{33}{25}\)

----------------------------

\(\dfrac{80}{99}+\dfrac{2}{99}\)

\(=\dfrac{80+2}{99}\)

\(=\dfrac{82}{99}\)

------------------------------

\(\dfrac{7}{5}+\dfrac{5}{7}\)

\(=\dfrac{49}{35}+\dfrac{25}{35}\)

\(=\dfrac{49+25}{35}\)

\(=\dfrac{74}{35}\)
