Question
Check whether the following quantities form a proportion or not?
`1 1/2, 3 1/4, 4 1/2 "and" 9 3/4`
Solution
`1 1/2, 3 1/4, 4 1/2 "and" 9 3/4` are in proportion
if `1 1/2 xx 9 3/4 = 3 1/4 xx 4 1/2`
`=> 3/2 xx 39/4 = 13/4 xx 9/2`
`=> 117/8 = 117/8` which is true
Hence `1 1/2, 3 1/4, 4 1/2 "and" 9 3/4` are in proportion.
