If

11 boxes of chocolates contain
220
220 chocolates in total, calculate how many chocolates will be in
5
5 boxes.
chocolates.
To find out how many chocolates will be in 5 boxes, we can use the proportion:
11 boxes / 220 chocolates = 5 boxes / x chocolates
To solve for x, we can set up and solve the proportion:
11/220 = 5/x
To solve for x, we can cross multiply and solve for x:
11x = 220 * 5
11x = 1100
Dividing both sides by 11, we get:
x = 100
Therefore, there will be 100 chocolates in 5 boxes.
Using that 3 feet = 1 yard, calculate the conversion below. It may help to set up a proportion.
16 yards =
feet
To convert yards to feet, we can set up the following proportion:
1 yard / 3 feet = 16 yards / x feet
To solve for x, we can cross multiply and solve for x:
1 * x = 3 * 16
x = 48
Therefore, 16 yards is equal to 48 feet.
Use the conversion ratio 1 liter equals 1,000 milliliters to complete the problem. It may help to set up a proportion.
A cylinder holds 6,750 milliliters. How many liters does it hold?
1 liter = 1,000 milliliters
A
67.5
B
6,750,000
C
7,750
D
6.75
To calculate how many liters the cylinder holds, we can set up the following proportion:
1 liter / 1,000 milliliters = x liters / 6,750 milliliters
To solve for x, we can cross multiply and solve for x:
1 * 6,750 = 1,000 * x
6,750 = 1,000x
Dividing both sides by 1,000, we get:
x = 6.75
Therefore, the cylinder holds 6.75 liters. The correct answer is option D.
Use the conversion ratio 1 kilometer equals about 0.62 miles to solve the following problem. It may help to set up a proportion.
An airplane travels about 900 kilometers per hour. What is the airplane's speed in miles per hour?
1 kilometer
0.62 miles
A
558
B
1451.6
C
899.38
D
1240
To calculate the airplane's speed in miles per hour, we can set up the following proportion:
1 kilometer / 0.62 miles = 900 kilometers / x miles
To solve for x, we can cross multiply and solve for x:
1 * x = 0.62 * 900
x ≈ 558
Therefore, the airplane's speed is approximately 558 miles per hour. The correct answer is option A.
