 Equivalent Fractions have the same value, even though they may look different. These fractions are really the same:1/2 ....... 2/4 .......... 4/8 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: 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. Maths coordinator

 you are welcome my dear, the division like the multiplication exactly .You divide both N and D by a factor for both of them untill you get the simplest form of the fraction. the difference is you should look for a common factor between both N and D. I hope you enjoy practicing maths. Maths coordinator
