Final answer:
To find equivalent fractions to 2/3 using a number line, divide the number line into equal parts. The equivalent fractions to 2/3 are 4/6 and 6/9.
Step-by-step explanation:
To find equivalent fractions to 2/3 using a number line, we need to divide the number line into equal parts. In this case, we will divide it into 3 equal parts. We start at 0 and mark the point representing 2/3. Then, we can observe that the other two equal parts on the number line will represent the equivalent fractions 4/6 and 6/9. So, the equivalent fractions to 2/3 are 4/6 and 6/9.
