Question

18 : 9/7
35/9 : 15
 75/32 : 18/25 : 27/8
46/35 : 23/27 : 15/14

Answer 1

`18 : 9/7 = 18 xx 7/9 = (18xx7)/9 = 2xx7=14`

 

`35/9 : 15 = 35/9 xx 1/15 = (35xx1)/(9xx15) = (7xx1)/(9xx3)=7/27`

 

`75/32 : 18/25 : 27/8`

`= 75/32 xx 25/18 xx 7/28`

`=(75xx25xx7)/(32xx18xx28)`

`=625/648`

 

`46/35 : 23/27 : 15/14`

`=46/35 xx 27/23 xx 14/15`

`=(46xx27xx14)/(35xx23xx15)`

`=(2xx27xx14)/(35xx1xx15)`

`=36/25`

Answer 2

= 18/1 x 7/9 = 14

= 35/9 x 1/15 = 7/27

= 75/32 x 25/18 x 8/27 = 625/648

= 46/35 x 27/23 x 14/15 = 36/25

Answer 3

18 : 9/7=14
35/9 : 15=7/27
 75/32 : 18/25 : 27/8=625/648
46/35 : 23/27 : 15/14=36/25

Answer 4

\(18:\dfrac{9}{7}=18\times\dfrac{7}{9}=\dfrac{126}{9}=14.\)

\(\dfrac{35}{9}:15=\dfrac{35}{9}\times\dfrac{1}{15}=\dfrac{35}{135}=\dfrac{7}{27}\)

\(\dfrac{75}{32}:\dfrac{18}{25}:\dfrac{27}{8}=\dfrac{15000}{15552}=\dfrac{625}{648}\)

\(\dfrac{46}{35}:\dfrac{23}{27}:\dfrac{15}{14}=\dfrac{17388}{12075}=\dfrac{36}{25}\)
