Question

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

Answer 1

Answer:

Games won by his friend = 3

Step-by-step explanation:

Given data:

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 data:

                          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
