Paula says that 2/3 is equivalent to 4/9 because 4 is a multiple of 2 and 9 is a multiple of 3. explain her error.
valentina_108 [34]

Answer:

Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.

Step-by-step explanation:

Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.

4/9 is basically obtained when we multiply the denominator of 2/3 by 2 and denominator by 3, which is wrong.

Thus, the correction is as follows:

Given the fraction

\frac{2}{3}

Multiply the nominator and denominator of the fraction by 2

\frac{2\times 2}{3\times 2}=\frac{4}{6}

Thus, the 4/6 is the correct equivalent expression of 2/3.

3. Solve each equality or inequality:<br> a. |8x-6|= 0
larisa [96]

Answer:

x = 3/4

Step-by-step explanation:

Step 1: Find possibilities.

  • We know one possibility: 8x - 6 = 0. This is because 0 cannot be positive or negative.

Step 2: Solve possibility 1.

  • 8x - 6 = 0
  • 8x - 6 + 6 = 0 + 6 (Add 6 to both sides)
  • 8x = 6
  • \frac{8x}{8} =\frac{6}{8} (Divide both sides by 8)
  • x = \frac{3}{4}

Therefore, x = 3/4.
