How To Add Fractions And Reduce To Lowest Terms

write 15:25 as a fractionin simplest form. so 15 to 25 is just a ratio,and we can write it. so they've given us 15 to 25. and you can write this ratio asa fraction, as 15 over 25. and if we want to put this insimplest form, we just have to

How To Add Fractions And Reduce To Lowest Terms, think about what is the largestnumber that divides into both 15 and 25? or what is their greatestcommon factor? when you just eyeball it, yousay, well, 5 goes into both of

them, and i'm pretty sure that'sthe largest number that divides into both, so let'sdivide both by 5. if there is a larger number,then we might be able to see it once we've simplifiedit a little bit more. so let's divide the numeratorand the denominator by 5 and see what we get. so now we get 15 dividedby 5 is equal to 3. and 25 divided by 5 is equalto 5, and now we have 3/5. 3 and 5 don't share any commonfactors greater than 1, so it

is in simplest form. so we've done what they asked. we've written it as a fractionin simplest form. we could also write this, ifwe want to write it in this type of notation, as 3:5.
