Percentage Calculations and Equations

The video tutorial covers solving percentage problems using bottles C and D as examples. It explains how to calculate percentages, represent problems with equations, and solve them. The tutorial also demonstrates using calculators for verification and provides instructions for practice problems.

If Bottle C contains 150% of the water in Bottle D, and Bottle D has 12 ounces, how much water is in Bottle C?

• 24 ounces

• 36 ounces

• 18 ounces

• 30 ounces

What percentage of Bottle B's water is in Bottle D if Bottle B has 16 ounces and Bottle D has 12 ounces?

• 60%

• 50%

• 80%

• 75%

What is 60% of 400?

• 300

• 87

• 240

• 120

Is 60% of 200 equal to 87?

• Yes

• No

• Sometimes

• Cannot be determined

How do you express 60% of a number X as an equation?

• X/0.6 = 87

• 60X = 87

• 0.6X = 87

• 0.6 + X = 87

What is the value of X if 60% of X equals 87?

• 145

• 150

• 160

• 170

If 38% of E equals 190, what is the value of E?

• 540

• 560

• 500

• 520

What is the first step in solving the equation 0.6C = 43.2?

• Multiply both sides by 0.6

• Divide both sides by 0.6

• Add 0.6 to both sides

• Subtract 0.6 from both sides
