Exploring Percent Equations in 7th Grade Math

What is the main goal of this video tutorial?

• To practice multiplication and division

• To solve percent increase and decrease problems using equations

• To learn about different languages

• To understand the history of mathematics

What structure is emphasized for solving percent problems?

• A - B = C

• A + B = C

• X percent of A is B

• X times A equals B

If Matt travels 25% fewer miles on the highway, what percent of the original distance does he travel?

• 100%

• 75%

• 50%

• 25%

How many miles did Matt travel on the highway if he traveled 36 miles and this is 75% of the original distance?

• 24 miles

• 48 miles

• 36 miles

• 27 miles

What is the equation to find the original distance if 75% of it is 36 miles?

• A / 0.75 = 36

• 0.75 * A = 36

• A + 0.75 = 36

• A - 0.75 = 36

What is the first step to solve for the original distance if 75% of it is 36 miles?

• Divide 36 by 0.75

• Multiply 36 by 0.75

• Subtract 0.75 from 36

• Add 36 to 0.75
