Intro to proportions

What does it mean for two fractions to be equivalent?

• They have the same numerator and denominator.

• They represent the same value or proportion, even if they have different numerators and denominators.

• They can be simplified to the same fraction.

• They are both greater than one.

What is the formula for finding a missing value in a proportion?

• If a/b = c/d, then ad = bc.

• If a + b = c + d, then a = c - b.

• If a/b = c/d, then a = (b * c) / d.

• If a/b = c/d, then a = b + c.

What is the cross-multiplication method?

• Cross-multiplication involves adding the numerators of two fractions.

• Cross-multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction to find a solution.

• Cross-multiplication is a method used to simplify fractions by dividing them.

• Cross-multiplication is a technique for finding the least common multiple of two numbers.

How do you solve a proportion?

• Cross-multiply the terms and then solve for the unknown variable.

• Add the two fractions together and simplify.

• Multiply both sides by the same number.

• Subtract the smaller number from the larger number.

How can you check if two fractions are equivalent?

• By adding the fractions and comparing the sums.

• By cross-multiplying and seeing if the products are equal.

• By finding a common denominator and comparing the numerators.

• By converting the fractions to decimals and comparing them.
