Question

4) Brazil has won one of the last

six world cup championships.
If they win this year, what will
their winning fraction be?

Answer 1

2/6, since they have already won 1 of the last 6, just add the one they could or will win to the numerator.

Answer 2

`(2)/(7)`

Explanation:

`\boxed{\sf Fraction=(part)/(whole)}`

If Brazil has won one of the last six world cup championships, then their "winning fraction" will be:

• 
  `\sf (part)/(whole)=(1)/(6)`

If they win this year, Brazil's number of wins will be 2 and the total number of world cup championships is 7. Therefore, their "winning fraction" will be:

• 
  `\sf (part)/(whole)=(2)/(7)`
