The trick here - apart from the usual one, of finding a common denominator - is to "lend" one from the whole part, and add it to the fraction. Since one whole is 3/4, you add 4/4, to get 7/4. Then (and after converting everything to the common denominator), you can easily subtract the fractional part.
14/8 - 7/8 = 7/8
3 over 4
3 4/7 minus 1/7 is 3 3/7
1 whole and 1 over 10
The answer is 1/4. 1 whole would be 4/4 (4 over 4) so subtracting 3/4 (3 over 4) gives the result.
42/3 - 14/5 = 43/15 or 213/15
3 over 4
3 4/7 minus 1/7 is 3 3/7
1 whole and 1 over 10
3 − 31/4 = 11/4
The answer is 1/4. 1 whole would be 4/4 (4 over 4) so subtracting 3/4 (3 over 4) gives the result.
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.
42/3 - 14/5 = 43/15 or 213/15
1 minus 1/4 = 3/4
4/7 minus 3/4 is -5/28
[(1-4)/9] = [(-3)/9] = -1/3
It is 2 11/20.
4/9 minus 3/4 equals -11/36
