we are going to use these pieces of fruit and this computer model to learn about fractions, the subtraction of fractions, let ustake a look. we are going to start with the fruit. we have five pieces of fruit three of them are tangerines and two of them are lemons.
How To Add Fractions Powerpoint, i am want to eat this fruit, but you know something? lemons ones are not great to just pick up and eat so i am going to remove them from the collection. i am takingaway two of the five parts or 2-fifths and that leavs me with 3-fifths remaining. 5-fifths minus the 2-fifths i have 3-fifthsremaining.
let us take a look and see how that works withthe models. i started with five pieces of fruit and they are represented by this collection of five,everything being shaded, and i am removing or subtracting 2-fifths. sothere is my 2-fifths and if i subtract them what is left? one, two, three, so i subtracted two lemons and i am leftwith the three tangerines. so here is what i am left with. there is my answer so 5-fifths minus 2-fifths equals 3-fifths let us take a look and see how we write that.
we started with 5-fifths, we subtracted 2-fifths,and we ended up with 3-fifths. in all cases, are collection is five, thedenominator is five, that is the total collection. the total number of pieces of fruit we startedout with all five in the numerator. 5-fifths; we took away 2-fifths and we ended up with 3-fifths. 5-fifths minus 2-fifths equals 3-fifths.
