Final answer:
To build a fraction equivalent to (2)/(7) using (6)/(6) for 1, multiply both the numerator and denominator of (2)/(7) by 6 to get (12)/(42).
Step-by-step explanation:
Fractions are a way of representing a part of a whole. They consist of two numbers separated by a horizontal line, where the number above the line is called the numerator, and the number below the line is called the denominator. The fraction is read as "numerator over denominator.
To build a fraction equivalent to (2)/(7) using (6)/(6) for 1, we can multiply both the numerator and denominator of (2)/(7) by the same number to create an equivalent fraction. Since (6)/(6) is equivalent to 1, we can multiply (2)/(7) by 6 to get (12)/(42).
