Sure, I can help you with that! Here are some common problems involving decimals that are money-related and how to solve them:
Step-by-step explanation:
Calculating percentages: To calculate a percentage of a given amount, multiply the amount by the percentage as a decimal. For example, to find 20% of $50, multiply 50 x 0.20 = $10.
Adding and subtracting decimals: When adding or subtracting decimals, line up the decimal points and add or subtract as usual. For example, $12.45 + $8.32 = $20.77.
Multiplying decimals: When multiplying decimals, ignore the decimal points and multiply the numbers as if they were whole numbers. Count the total number of digits to the right of the decimal point in both numbers, and then place the decimal point in the product so that the total number of digits to the right of the decimal point is the same as the sum of the digits in the two original numbers. For example, $5.25 x 2.5 = $13.125.
Dividing decimals: When dividing decimals, move the decimal point in the divisor (the number you're dividing by) to the right until it becomes a whole number. Then, move the decimal point in the dividend (the number you're dividing into) the same number of places to the right. Divide as usual. For example, $16.80 ÷ 3 = $5.60.
