Solving a proportion using the cross product ex 7, 8/5 = (4/3x)

The video tutorial demonstrates how to solve a proportion using the cross product method. The instructor explains the process of multiplying across the equal sign, simplifying the equation, and solving for the variable X. The final solution is simplified to X = 5/6, and the instructor emphasizes the importance of writing out steps to avoid mistakes.

What is the first step in solving a proportion using the cross product method?

• Add the numbers on both sides

• Multiply across the equal sign

• Subtract the smaller number from the larger

• Divide both sides by the same number

When applying the cross product to the equation, what is the result of 8 multiplied by 3X?

• 15X

• 32X

• 24X

• 20X

What is the result of multiplying 5 by 4 in the given proportion?

• 25

• 10

• 15

• 20

What is the next step after obtaining 24X = 20 in solving for X?

• Subtract 20 from both sides

• Divide both sides by 24

• Multiply both sides by 24

• Add 4 to both sides

What is the simplified form of X after dividing both sides by 24?

• X = 2/3

• X = 3/4

• X = 4/5

• X = 5/6
