Fractions and Decimals: Money Math: Addition (2024)

FAQs

How do you solve addition of fractions and decimals? ›

There could be two ways of adding a fraction to a decimal. (1) Convert fraction to the decimal format and add. If desired or required, the sum can again be converted into fraction. (2) Convert the decimal to a fraction and then add two fractions together.

Does 6 go into 15? Yes, two times.

Fractions (and their decimal representation) represent values relative to a whole (for example, one whole dollar). Quantities represented as a decimal are fractions limited to base ten denominators (i.e.: tenths, hundredths, thousandths, etc.) Standard representation of coin values are expressed as decimal hundredths.

Step 1: Write the decimal numbers as fractions. For example, if you want to find 0.6 + 0.15, convert 0.6 and 0.15 into fractional numbers. Step 3: Add the numerators. Step 4: Write the sum as a decimal number.

A dollar is a whole amount and is written to the left of the decimal. Cents are parts of a dollar and we write them to the right of the decimal. As you can see, to form the whole part (eleven dollars), we use a $10 bill and a $1 coin. For the decimal part, (fifty-seven cents), we use five 10¢ coins and seven 1¢ coins.

– Division is the process of breaking a number into equal parts and finding how many equal parts can be made. – We indicate division using ➗.

The answer is 2. How did we get here? We identify 4 as the dividend and 2 as the divisor, and place them in the division bar. We ask: “How many times can 2 go into 4?” We determine this using the “count by twos” method, which shows us that 2 goes into 4 a total of two times.

Answer and Explanation:

16 2/3 times 6 equals 100. The solution is as follows: Convert the word problem to an equation by substituting 'times' with multiplication, substituting 'what' with the variable 'Y' and substituting 'equals' with an equal sign: Y x 6 = 100.

Money Is a Special Decimal

No matter how big the value gets, you can only have two decimal places. One cent is 0.01. You can't give someone less than one cent if you hand them bills and coins. There are values less than a cent when you start figuring out tax or interest.

Exchange of Money: Most of our currencies contain fractions in the form of decimals. For example, we use dollars in the US, and other countries may have some other currency. So to interchange money, we take the help of fractions.

How do we solve equations that contain fractions and decimal numbers? ›

But decimals can also be expressed as fractions. For example, 0.3 = 3 10 0.3 = 3 10 and 0.17 = 17 100 0.17 = 17 100 . So, with an equation with decimals, we can use the same method we used to clear fractions—multiply both sides of the equation by the least common denominator.

TO ADD OR SUBTRACT DECIMALS:

1) Line up the decimal points vertically. Fill in any 0's where necessary. 2) Add or subtract the numbers as if they were whole numbers. 3) Place the decimal point in the sum or difference so that it lines up vertically with the numbers being added or subtracted.
