1. A fraction simply tells us how many parts of a whole we have. You can recognize a fraction by the slash that is written between the two numbers. We have a top number, the numerator, and a bottom number, the denominator. For example, 1/2 is a fraction. ... The 1 is the numerator, and the 2 is the denominator.
2. A decimal is a fraction written in a special form. Instead of writing 1/2, for example, you can express the fraction as the decimal 0.5, where the zero is in the ones place and the five is in the tenths place. Decimal comes from the Latin word decimus, meaning tenth, from the root word decem, or 10.
3. fraction to a decimal:
Divide the denominator (the bottom part) into the numerator (the top part):
1/4 = 1 4.00 = 0.25
A fraction to a percent:
Multiply the fraction by 100 and reduce it. Then, attach a percent sign.
1/4 x 100/1 = 100/4 = 25/1 = 25%
A decimal to a fraction:
Starting from the decimal point, count the decimal places. If there is one decimal place, put the number over 10 and reduce. If there are two places, put the number over 100 and reduce. If there are three places, put it over 1000 and reduce, and so on.
0.25 = 25/100 = 1/4
A decimal to a percent:
Move the decimal point two places to the right. Then, attach a percent sign.
0.25 = 25%
A percent to a decimal:
Move the decimal point two places to the left. Then, drop the percent sign.
25% = 0.25
A percent to a fraction:
Put the number over 100 and reduce. Then, drop the percent sign.
25% = 25/100 = 1/4

Answer:
1.The definition of a fraction is a mathematical expression with a numerator and a denominator, a disconnected piece or a small part of something. An example of fraction is one third. An example of fraction is a piece of glass that fell from a broken window. ... An expression that indicates the quotient of two quantities.
2.A decimal is a fraction written in a special form. Instead of writing 1/2, for example, you can express the fraction as the decimal 0.5, where the zero is in the ones place and the five is in the tenths place. Decimal comes from the Latin word decimus, meaning tenth, from the root word decem, or 10.
3.Just like when we converted a fraction into a decimal, we'll divide the numerator by the denominator. 3 divided by 6 equals 0.5. We've turned our fraction into a decimal. Now we'll turn the decimal into a percent by moving the decimal point two spaces to the right.
4. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.
5.Step 1 - Leave the whole number 1 as is.
Step 2 - Write the fraction in decimal form. First, we need to convert 1/2 into tenths; 1/2=x/10. ...
Step 3 - Write the full decimal form. Write the whole number with the decimal form of the fraction.
