Okay, so what exactly are decimals? Simply put, they're a way of representing numbers that are not whole. Think of them as fractions in disguise. They’re everywhere! From the price of your favourite chicken rice ($3.50, anyone?) to measuring ingredients for baking, decimals are a part of our daily lives.
Interesting Fact: Did you know that the concept of decimals dates back to ancient civilizations? But it was a chap called Simon Stevin, a Flemish mathematician, who really popularised them in Europe in the 16th century. So, we're talking about some serious history here!
Adding and subtracting decimals can seem daunting, but it's actually quite straightforward. The key is alignment! Line up the decimal points, and then add or subtract as you would with whole numbers. It’s like making sure all the soldiers are standing in a straight line before battle, lah!
Example:
Let's say you're buying a bowl of noodles for $4.20 and a drink for $1.50. To find the total cost, you'd add $4.20 + $1.50, making sure to line up those decimal points. The answer? $5.70. Easy peasy!
Multiplying decimals involves a slightly different approach. First, multiply the numbers as if they were whole numbers. Then, count the total number of decimal places in the original numbers and put that many decimal places in your answer.
Example:
Imagine you're buying 2.5 kg of apples at $3.00 per kg. Multiply 25 (2.5 without the decimal) by 3 (3.00 without the decimals) to get 75. Since there's a total of two decimal places (one in 2.5 and one in 3.00), the answer is $7.50.
Dividing decimals can be a bit trickier, but here's a pro-tip: make the divisor (the number you're dividing by) a whole number. You can do this by multiplying both the divisor and the dividend (the number being divided) by the same power of 10. Then, divide as usual.
Example:
Let's say you have 7.2 litres of juice and want to divide it equally among 4 people. You divide 7.2 by 4.
