HOW |
How two divide fractions Change the division symbol in to a multiply symbol. ⅔ divided by ⅘ - ⅔ multiplied by ⅘ Write the precipice of the second fraction. The reciprocal is just the fraction being switched around for example 4/5 - 5/4 .2/3 multiplied by 5/4 Multiply it with all the changes you have made so far Multiply straight across 2/3 multiplied by 5/4 =10/12. Reduce if possible 10/12 10 divided by 2 =5 -12 divided by 2 =6 ⅚ Find greatest common factor then divide that number to top and then bottom If they do not have a common factor besides one you can not Dividing the fractions.
How to add fractions
Find a common denominator ⅔ +¼ and 3 multiplied by 1 =3 then those are the new numerators 8/12+3/12 .multiply the denominators together to get a new denominator for both fractions 3 multiplied 4= 12 then multiply the denominator of the fractions to the numerator of the other fraction 4 multiplied 2 = 8 .⅔ + ⅙multiply top and bottom of firs fraction by 2 you get 4/6 +⅙.Then add the top numbers but not the bottom 8/12+3/12=11/12.Reduce if possible If only common factor is 1 you can not reduce if the are numbers that are right next to each other than you no you cannot reduce but if not then you have to find the greatest common factor between them.
