13. Find 3 fractions that are equivalent to 2/3. Explain how you found your answers​
Rashid [163]

Answer:

\frac{4}{6} =\frac{6}{9}= \frac{8}{12}

Step-by-step explanation:

<em>I'm assuming this is asking for 3 separate fractions that are each equal to 2/3</em>

Remember, multiplying the top and bottom of a fraction by a number will not change the fraction.

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

\frac{2}{3} *\frac{3}{3} =\frac{6}{9}

\frac{2}{3} *\frac{4}{4} =\frac{8}{12}

These three fractions are all equal to 2/3
