whole as a percentage.
N.ME.05.10 Understand a fraction as a statement of division, e.g., 2 ÷ 3 = 2/3, represent simple fractions with pictures.
N.ME.05.11 Given two fractions, express them as equivalent fractions with a common denominator, but not necessarily a least common denominator, e.g., 1/2 = 4/8 and 3/4 = 6/8; use denominators less than 12, or factors of 100.
N.FL.05.12 Find the product of two unit fractions with small denominators, using area model.
N.FL.05.13 Divide a fraction by a whole number and a whole number by a fraction, using simple unit fractions.
N.FL.05.14 Add and subtract fractions with unlike denominators of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 100, using the common denominator that is the product of the denominators of the 2 fractions, e.g., 3/8 + 7/10 = ((3x10)+(7x8))/80 = (30+56) ÷ 80 = 86/80.
