Question

Tim plays a computer game.

Each game is a win or a loss.
He wins three fifths of his first 40 games.
He then wins his next 12 games.
For all 52 games, work out the ratio wins : losses
Give your answer in its simplest form.​

Answer 1

9:4

Explanation:

of his first 40 games: 3/5 *40=3*8=24 wins

=> of his first 40 games : 24 wins and 40-24=16 losses

next 12 games: 12 wins

so, for all 52 games: 24+12=36 wins and 16 losses

36 wins and 16 losses

wins: losses=> 36:16=> 9:4
