Lesson 1: Common fractions and decimals

# Common fractions and decimals

Explores the concept of converting common fractions (1/5, 1/4, 1/2) into decimals. Learn the importance of understanding these conversions for real-life applications and for working with multiples of these fractions.

• how do you convert a percentage into a decimal?
• Move the imaginary decimal point two spaces to the left.
100% -> 1.00
50% -> 0.50
1% -> 0.01
You could also divide a percentage by 100 to get the decimal.
100%/100 is 1.00
50%/100 is 0.50
1%/100 is 0.01
• I tipped in 1/4 = 25/100 but it’s says it’s wrong why is that
• that is true but they are asking you to rewrite it as a decimal. 1/4 = .25
• Ok, my mom helped me with this. This is basically what she said:
0.4 is equal to 4/10 (four tenths). Once you have it in fraction form, just simplify the fraction.
Hope that helps! :-)
• can you times a decimal
• Yes. If you want to multiply a decimal, you have to just multiply the numbers, and put the decimal point in after. For example, 4 times 0.2 is 0.8.
• I don't get how a fraction can be converted into a decimal.
• The simplest method to transform a fraction number to a decimal value is to simply divide the numerator by the denominator to get the decimal value. The numerator is the top number and the denominator is the bottom.
• i like math but not this!
• this is easy :)
• I can understand converting fractions to decimals but not decimals to fractions :(
• Converting decimals to fractions is actually easier. It's all in how you SAY the decimal. For example:

0.2 is pronounced two tenths and then is written 2/10
0.35 is pronounced thirty five hundredths an then is written 35/100
