Comparing Fractions
by:James yen
This week, we were doing a doc of comparing fractions. we have different strategies and at the end, we needed to complete a work sheet.
Strategy Name | Explanation | Example |
#1
Equal Denominator |
If they have different fractions and all of the denominators is the same, look at the numerator and see which number is the biggest to smallest, you will find out. | 2/5 4/5 7/5
Which is the biggest fraction? erj da = same |
#2
Equal Numerator |
If the numerator is closer to the denominator, it is the largest. | 4/5 4/7 4/1309
Which is the largest fraction? 4 : 7= +3 4 : 1309= +1305 |
#3
knowledge of half |
You need to divide the denominator and the numerator.do each fraction the same thing and you can see the difference of each fraction. | 7/15 6/25
Which is the biggest? 25-6=4.5 |
#4
Bench mark of 1 |
When the numerator is bigger than the denominator, it will show that other proper fraction and equal fractions is less than the improper fraction. | 2/4 5/4 6/6
Which fraction is bigger? 2/4 = 2/4 6/6 = 1 whole 5/4 = 1 whole and one fourth |
#5 missing piece | When the denominator is different to other fraction, check the numerator, and if each numerator is 1 number less from the denominator, check the largest numerator, once you see it, that is the answer for the largest. | ½ 6/7 12/13 12 is the biggest, so that means 12/13 is the biggest. |
