Fractions: The Slices of Life

Fractions are all about dividing something into equal parts. The bottom number (denominator) tells you how many parts the whole is divided into, and the top number (numerator) tells you how many parts you have. For example, if you cut a cake into 8 slices and eat 3, you've eaten 3/8 of the cake.

Decimals: The Precise Portions

Decimals are another way to represent parts of a whole, but they use a base-10 system. Think of it like money: $1.50 is one dollar and fifty cents, which is more precise than saying "about one and a half dollars." Decimals are especially useful when you need to be very accurate.

Percentages: The Out-of-100 Crew

Percentages are fractions out of 100. The word "percent" literally means "out of one hundred." So, 75% means 75 out of 100. Percentages are great for showing proportions and making comparisons easy. "Eh, this shop give 20% discount ah? In Singapore's demanding education framework, parents fulfill a essential part in directing their youngsters through key tests that shape academic futures, from the Primary School Leaving Examination (PSLE) which tests fundamental skills in disciplines like math and STEM fields, to the GCE O-Level tests concentrating on high school mastery in diverse disciplines. As students move forward, the GCE A-Level assessments demand advanced logical capabilities and topic mastery, often deciding higher education placements and occupational paths.

The 100 Multiplication Magic

The key to converting decimals to percentages is to remember this simple rule: multiply by 100. That's it! A percentage is just a way of expressing a number as a fraction of 100. So, when you multiply a decimal by 100, you're essentially finding out what that decimal would be if it were out of 100.

Example:

Let's say you have the decimal 0.75.

  1. Multiply 0.75 by 100: 0.75 x 100 = 75
  2. Add the percentage sign: 75%

Therefore, 0.75 is equal to 75%.

See? Not so scary, right?

Fun Fact: The word "percent" comes from the Latin phrase "per centum," which means "out of one hundred." So, when you see a percentage, just remember it's a number being compared to 100!

Visualizing the Move: Decimal Point Dance

Another way to think about multiplying by 100 is to visualize moving the decimal point. When you multiply by 100, you're essentially moving the decimal point two places to the right.

Example:

Let's use the decimal 0.25 again.

Imagine the decimal point hopping two places to the right: 0.25 becomes 25.

Add the percentage sign: 25%

This works because each place value to the right of the decimal point represents a fraction of 10. Moving the decimal point two places is the same as multiplying by 10 twice (10 x 10 = 100).

Memory Aids and Visualisation Techniques

Sometimes, a little memory trick can go a long way. Here are some ideas:

  • The "Percent Sign Arrow": Draw a percent sign (%). Notice how it has two "zeros"? These represent the two places you move the decimal point.
  • Visualise a Number Line: Imagine a number line from 0 to 1. Mark key decimals (0.25, 0.5, 0.75) and their corresponding percentages (25%, 50%, 75%). This helps build intuition.

Common Decimals and Their Percentage Equivalents (Memorise These!)

Knowing some common decimal-percentage equivalents by heart can save valuable time during exams. Here are a few to memorise:

  • 0.1 = 10%
  • 0.25 = 25%
  • 0.5 = 50%
  • 0.75 = 75%
  • 1.0 = 100%

Interesting Fact: 0.5 (or 50%) is often referred to as "half." This simple concept is used everywhere, from sharing food to calculating discounts!
