Solution
Rafiq exercised = `3/6` of an hour
Rohit exercised = `3/4` of an hour
`3/6, 3/4`
Convert these into like fractions
`3/6 = (3 × 2)/(6 × 2)`
= `6/12`
`3/4 = (3 × 3)/(4 × 3)`
=`9/12`
Clearly, `9/12 > 6/12`
∴ `3/4 > 3/6`
Therefore Rohit exercised for a longer time than Rafiq.

[This game is to be played in groups of 4. Each player has to make a circle as shown. Each one has to make 15 tokens on slips on paper.
Write `1/2, 1/3, 1/4, 1/6, 1/12, 2/12, 3/12, 4/12,...11/12` to make your tokens.
Shuffle, the tokens and make a pile in the middle of the group. Now you are ready to start the game.
The first player takes a token from the pile, colours that part of the picture, and puts the token under the pile. The next player does the same, and so on. The winner is the one who first colours the circle completely.]
