Will was playing checkers with a friend the ratio of games was 3:1 won nine games how many games did his friend win

Games won by his friend = 3

Step-by-step explanation:

Given dа ta:

Ratio of games winning = 3:1

Total games won by Will = 9

Total games won by his friend = ?

Solution:

Assume games won by friends = x

So according to dа ta:

3:1 = 9:x

= 3/1 = 9/x

By cross multiplying:

= 3x = 9 * 1

By dividing 3 to the both sides of equation:

= 3x/3 = 9/3

= x = 3

Games won by friend = 3
