Write each as a percent. Round to the nearest tenth of a percent
3) 0.072 = 0.072 X 100 = 7.2 %
4) 3.58 = 3.58 X 100 = 358 %

Examples of work problems
1) The price of a laptop was reduced by 30 % to $ 120. What was
the original price?
100% — 30% = 70%
X — 100%
$ 120 — 70%
X = (100 % X $ 120) / 70 %
X = $171.43 was the original price of the laptop
2) Two years ago, a ticket to the football game was $20. This
year, the price has been increased by 60%. What is the price
of this ticket this year?
60 % X $ 20 = (60/100) X $20 = $ 12
$ 20 + $ 12 = $ 32
The price of the ticket this year is $ 32
