I can make equal groups of eighteenths on a fraction strip to form an equivalent fraction in simplest form. I can make equal groups of eighteenths on a number line to form an equivalent fraction in simplest form. I can divide the numerator and denominator of a fraction by the same number (a common factor) to make an equivalent fraction made from fewer but larger unit fractions. I can use the prime factorization to find common factors of the numerator and denominator. Then I can use what I know about the Identity Property of Multiplication. 10 10 ÷
