4 Steps to Add Rational Numbers in Fraction Form | Grade 7 Math | 7.NS.A.1 💚

In this video we will learn 4 steps to add rational numbers in fraction form. The four steps are - Step 1: If necessary, write mixed numbers as improper fractions. Step 2: If necessary, rewrite fractions to have a common denominator. Step 3: Add the numerators using integer rules and keep the denominator. (Same Signs Rule - Find the absolute value of the numerators. Add. Then, use the common sign from the original numerators.) (Different Signs Rule - Find the absolute value of the numerators. Subtract the smaller from the larger. Use the sign of the numerator that has the larger absolute value.) Step 4: If necessary, simplify the fraction. We will practice adding a negative fraction and a positive fraction, a positive fraction and a negative fraction, as well as a negative fraction and a negative fraction. We will review how to write a mixed number as an improper fraction, as well as how to write an improper fraction as a mixed number. We will also review how to find a common denominator to add. Student practice is provided. Exemplar solutions are modeled and explained. Purchase the Animated Google Slides used to make this video - https://www.teacherspayteachers.com/P...

For example, a hydrogen atom has 0 charge because its two constituents are oppositely charged. 7.NS.A.1.b Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts. 7.NS.A.1.c Understand subtraction of rational numbers as adding the additive inverse, p – q = p + (–q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts. 7.NS.A.1.d Apply properties of operations as strategies to add and subtract rational numbers.
