Equivalent Fractions

Equivalent Fractions have the same value, even though they may look different.
These fractions are really the same:

1/2 ....... 2/4 .......... 4/8 Smile
Why are they the same? Because when you multiply or divide both the top(N) and bottom(D) by the same number, the fraction keeps it's value.
The rule to remember is:
What you do to the numerator of the fraction
you must also do to the denimerator of the fraction !

So, here is why those fractions are really the same:

× 2 × 2

1 = 2 = 4
2 = 4 = 8


× 2 × 2
And visually it looks like this:

1/2 = 2/4 = 4/8


Here are some more equivalent fractions, this time by dividing:

÷ 3 ÷ 6

18 = 6 = 1

36 = 12 = 2



÷ 3 ÷ 6

If we keep dividing until we can't go any further, then we have simplified the fraction (made it as simple as possible).

Important: cheers
The N and D of the fraction must always be a whole number.
So, the number you pick to divide by must always divide evenly ( no remainders) for both the N and D numbers.
You only multiply or divide, never add or subtract, to get an equivalent fraction.
