Fractions Fraction is divided into 2 parts Numerator Denominator The numerator (the part) is being compared to the denominator (the whole)

Comparing Fractions Example: which is bigger: 3/8 or 5/12 ? Convert each fraction to a decimal. We can use a calculator (3÷8 and 5÷12) Anyway, these are the answers I get: 3/8 = 0.375, and 5/12 = So 5/12 is bigger.

HW Worksheet

Lesson... solve real-world problems involving the addition, subtraction, multiplication, and/or division of rational numbers? (7.NS.3)

Adding Fractions There are 3 Simple Steps to add fractions: Step 1: Make sure the bottom numbers (the denominators) are the same Step 2: Add the top numbers (the numerators), put the answer over the denominator Step 3: Simplify the fraction (if needed)

Subtracting Decimals Follows the same pattern as adding except you subtract the numerators.

Exit / Closure In math, why is it important to have the same denominator when adding and subtracting decimals?
