.25 25% Fractions Decimals Percents 1 Session Outcomes: To identify equivalences between fractions, decimals and percent.

To identify the relationship between fractions, decimals and percent. 2 What are fractions, decimals,and percents? Fractions, decimals and percents are different ways of representing part of a whole. We could say 50% of something, or , or 0.5. These are all the same quantity.

3 What are fractions? A fraction describes part of a whole when the whole is cut into equal parts. This circle has been cut into four equal parts. These equal parts are called fourths. A fourth is written as:

The three red sections equal three fourths, which would be written as: 4 Fractions can be converted into other forms Fractions

Percents Decimals 5 Same Value Different Forms A same value can be written in different forms. For example: fraction .5 decimal 50% percent

Convert a fraction into a decimal Divide the top of the fraction(numerator) by the bottom (denominator) of the fraction: = 12 = 0.5 7 Time to try converting a fraction into a decimal. 1. Fraction to convert = 3/4

2. Divide 3(numerator) 4(denominator) 3. Answer = .75 3/4 is equivlent to .75 8 Convert a decimal into a percentage Multiply the decimal by 100: 0.25 x 100 = 25% 9

Time to try converting a decimal into a percent. 1. Decimal to convert = .75 2. Multiply the decimal by 100 .75 x 100 3. Answer = 75% .75 is

equivalent to 75% 10 75 out of 100 squares are shaded. .75 or 75% or 75/100 (which reduces to ) 11
