Step 3.

Step 4 Reduce 75/100 = 3/4

To go from fraction to a decimal divide the numerator by the denominator.

3/4 equals 3÷4= .75

5/10 equals 5÷10= .50

How do you convert a fraction to a decimal, and then a decimal to a percent?

Let's look at the rules and then an example.

To go from decimal to percent simply multiply by 100

.75 x 100 = 75 %

.50 x 100 = 50 %

To move from percent back to fraction simply divide the percent by 100 then reduce.

75% = 75/100 then reduce = 3/4

50% = 50/100 ten reduce = 1/2

To go from a decimal to fraction.

Step 1: Write down the decimal over 1,

Step 2: Multiply both numerator and denominator by 10

for every number after the decimal point.

Step 3. Reduce the fraction

Example: Convert .75 to a fraction

Step 1 .75/1

Step 2. There are 2 numbers after the decimal point so...

Multiply the **decimal** by 100 for the ** percent**

For example: .75 x100 = 75%

.50 x100 = 50%

Hi welcome to MooMooMath. Today we are going to talk about going from a fraction to decimal to a percent. I’m going to take one example and convert the fraction to a decimal then to a percent. Let’s take three fourths. I will change that to a decimal which is .75 which is 75 %, let’s look at the rules. To go from a fraction to a decimal, take the top number (numerator) and divide it by the bottom number (denominator) the numerator goes inside the division bar and the bottom number (denominator) goes on the outside. To go from decimal to percent we will do a shuffle to the right. Move your decimal two places to the right. To go back from a percent back to fraction you can use the word percent (per meaning division and cent meaning 100) Let me demonstrate what I mean. We have three fourths. If I write that as division I will write three on the inside and four on the outside and I will divide. Four will not go into 3 so I add a decimal. Four will go into thirty 7 times. 7 times 4 equals is 28 subtract bring down a 2 and a zero so my decimal is .75. Now to go from decimal to percent move the decimal to the right two places. So it becomes 75.00. Next, to go from a decimal to a percent, I move my decimal two places to the right so that becomes 75 percent. Finally, to go to a fraction, remember percent (percent means division over 100.) All you need to do now is reduce by 5 so I divide the top and bottom by 5 so that becomes one twentieth. So that is my fraction. Now let’s do one more. So let’s go from percentage to decimal to fraction. Now to move from a percent to a decimal, instead of moving the decimal to the right, move it two places to the left. That would become .45. Remember 45% means 45 per which means to divide and cent means 100 so take 45 over 100. Reduce this fraction down which gives me 9 over 20. So there is my example. Hope this helps.
