This Power Point is a visual guide to adding and subtracting fractions. It also includes converting improper fractions and mixed numbers. This 38 page slide is filled with practice problems and resources!

Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).
Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) Γ· (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) Γ· (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (𝘒/𝘣) Γ· (𝘀/π˜₯) = 𝘒π˜₯/𝘣𝘀.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?
Interpret a fraction as division of the numerator by the denominator (𝘒/𝘣 = 𝘒 ÷ 𝘣). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, 𝘒/𝘣 + 𝘀/π˜₯ = (𝘒π˜₯ + 𝘣𝘀)/𝘣π˜₯.)
