Addition/subtraction of fractions. 4 1/2 - 1 2/3 Steps to take;- #1 ; convert to improper (top heavy) fractions. #2 ; bring to a common denominator #3 ; bring numerators to equivalent values #4 ; add/subtract numertors as appropriate #5 ; place over denomiator #6 ; bring back to a mixed number. Hence Step 1' 4 1/2 - 1 2/3 = 9/2 - 5/3 #2 ; 2 x 3 = 6 ( common denomiator) #3 ; 9 x3 =27 & 5 x 2 = 10 (Equivlent value numerators) #4 ; 27 - 10 = 17 #5 ; 17/6 #6 ; 17/6 = 2 5/6 The answer!!!! NB For addition of fractions , it is exactly the same process, except at step #4, you add the numertors.
5/6 − 1/6 = 2/3
18/20 + 8/20 - 5/20 = 21/20 or 1 and 1/20
4 over 5 is like 80'% of a pizza and 1 over 4 would only be having 25% of the pizza.
make the 1/4 into 2/8 Answer: 8 and 5/8
3/4 minus 1/5 is 11/20
It is: 4/7 minus 5/12 = 13/84
It is: 4/5 minus 1/2 = 3/10
5/6 minus 3/4 is 1/12
2 over 32 3 over 48 4 over 64 5 over 80
4/7 minus 3/4 is -5/28
4/7 minus 5/12 = 13/84
