Adding And Subtracting Rational Numbers
Storyboard Text
- adding subtracting rational numbers
- ADDITION:Step 1: Make denominators the sameStep 2: Add numerators over denominatorsStep 3: Simplify to standard form.
- SUBTRACTION:Step 1: Find the LCM of the denominatorsStep 2: Add the new numerators and write them as the resulting numeratorStep 3: write LCM of denominatorStep 4: Express rational number in lowest form.
- So adding rational numbers are easy to understand, it has some steps throughout the solving process.
- Dave, a store employee, wants to fit two fish tanks on one table. One fish tank is 1 foot wide and the other is 1/2 foot wide. When placed next to each other, what is the total width of the 2 tanks?(Answer as a fraction or whole number)1 = 1/2=1 1/2 ( the answer is in simplest form)so the total width is 1 1/2.
- A marine biologist measured first fish that was 5/6 foot long and a second fish that was 1/6 foot long. How much longer was the first fish?(Answer as fraction)
- Subtract numerators:5/6 - 1/6 = 4/6 So, the fish is 4/6 feet long
- Thank you class, have a nice day class dismissed.
