- Set up a ratio to represent the following: 10 quarters to 12 dimes to 16 nickels
- 1 quarter = 25 cents
- 1 dime = 10 cents
- 1 nickel = 5 cents
- i.e. 250 : 120 : 80
- Â Â Â Â Â Â 25 : 12 : 8
- Set up a ratio to represent the following: 10 quarters to 12 dimes to 16 nickels
-
- Set up a ratio to represent the following: one-half of an hour to 18 minutes
- 1hour = 60 minutes
- i.e. 30 minutes : 18 minutes
- 30:18 = 5:3
- Set up a ratio to represent the following: one-half of an hour to 18 minutes

- Solve: 2.18: 1.61 = k : 4.4
- 2.18/1.61=k/4.4
- K=2.18/1.61*4.4
- K=5.96
- Solve: 2.18: 1.61 = k : 4.4

- Students, A, B, and C occupy floor space of 50 m, 70 m, and 80 m,respectively. If the total rental for the space is $1000 per month, how much rent should student A pay?
- 1000 should be allocated to 50:70:80
- 1000/(50+70+80)
- 1000/200
- 5
- A should pay (50*5)=$250
- B should pay (70*5)=$350
- C should pay (80*5)=$400

- A clothing company has found that, based on past experience, $17.50 must be spent on labour costs for every $13.25 spent on materials. If a budget of the year 2005 is set at $231 875.00 for materials, calculate the amount that must be budgeted for labour.
- The ratio is 17.50:13.25=k:231875
- K=17.50/13.25*231875
- K = 306250
- the amount that must be budgeted for labour = $306250

- A buyer bought merchandise for $2900. If he sells the merchandise at 66 2/3% above cost, how much gross profit does he make?
- The merchandise increased 66 2/3 %.
- The profit he makes is 66 2/3% of 2900
- Ie. 2900/100*66 2/3 =1933.3
- The gross profit is $1933.3

- After an increase of 8%, the new amount was $875. What was the original amount?
- Therefore $875 is 108% of the original amount.
- Original price = 875/108*100=$810
- After an increase of 8%, the new amount was $875. What was the original amount?
