Expanded Notation to Standard Form

To convert an expanded notation to standard form, we need to calculate the value of the given expression.
Example: (6 × 100,000) + (5 × 1,000) + (2 × 10) = 600,000 + 5,000 + 20 = 605,020

Rounding and Earning Points

When earning points by rounding each purchase to the nearest dollar, we need to round the purchase amount to the nearest whole number.
Example: If Beth spent $342.70, she earns 343 points.
When using points for gas, we subtract the used points from the total points earned.

Comparing Fractions

To compare fractions, we need to find the equivalent decimals or convert both fractions to have the same denominator.
Example: To compare 4/9 with the given options, we can convert all fractions to decimals: 4/9 = 0.44, 2/3 = 0.67, 3/4 = 0.75, and 2/5 = 0.4.
Then, we can compare the decimal values to find the correct answer.
