There were 12 gaols scored during the game. team a scored 8/12 of the goals. team b scored 2 goals during the first half of the game. what fraction of the goals did team b score during the second half of the game

2/12 since the whole is 12, 12 is the denominator. since 2 is the amount of goals 2 is the numerator.

if you where drawing a picture, there would be 12 parts and 2 shaded

If 10 goals (8+2) had been scored already during the game that means there would be 2 goals (12-10) left to score.
This means that Team B scored 2 goals in the secound half of the match.
This can be written as 2/12 or 1/6 if you simplified it down.
