Examples: Algebraic Expression:
Twice a number increased by ten 2y + 10
Three times a number decreased by five 3k - 5
A number increased by 7 t + 7
p pizzas divided evenly amongst four p/4
In Pre-Algebra today, we reviewed dividing decimals when there is a decimal present in the divisor. We modeled two different methods:
- Move the decimal in the divisor to create a new number and move it the same number of times in the dividend.
- Multiply both the dividend and divisor by a power of ten to get rid of the decimal in the divisor.
