- Finding a quantity if the percentage is known
- If a percentage of a quantity is
known, to find the quantity we first
find the 1% (or 10%) and then we
multiply it to find the 100%.
- In one-day cricket match Ricky Ponting, Australia's
capitian, scored 102 runs, If this was 34% of the team's
runs, what did the team scored
- 34% of the runs = 102
1% of the runs = 102 ÷ 34
=3
- 100% of the runs = 3 x 100
= 300
- The Australian team scored 300 runs
- The Australian team scored 300 runs
- 100% of the runs = 3 x 100
= 300
- 34% of the runs = 102
1% of the runs = 102 ÷ 34
=3
