1 - 15 = -14
On the number line
...-15,-14 , =13 .... -2,-1- 0, 1,2,3, ...
Remember
For subtraction move to the left, and for addi
So if you star at '1' and move '15' places to the left (subtraction) you end up on '14'.
1-15= -14
2/3 = 10/15 and 1/5 = 3/15. 10/15 - 3/15 = 7/15 There's the answer
2/3 minus 6/10 = 1/15
2 and 1/3 minus 2/5 = 2 and 2/15
15y-15=0,y=1
7/10 minus 1/6 is 8/15
2/5 minus 1/15 is 1/3
It is: 2/3 minus 3/5 = 1/15
15 since 16-1=15
15 + 6 - 1 = 20
If you mean 2/5 minus 1/3 then it is 1/15
17/3 minus 15/4 is 1 11/12
1/3 minus 1/5 is 2/15
It is: 2 and 1/3 minus 2/5 = 29/15 or 1 and 14/15
x = 1
2/3 = 10/15 and 1/5 = 3/15. 10/15 - 3/15 = 7/15 There's the answer
1/8 - 1/15 = (1*15 - 8*1)/8*15. The answer is 7/120.
2 4/5 - 13/15 Subtraction of fractiopns. Steps to take #1 ; Bring both numbers to (iproper) factions #2 ; Bring the denominators to a common value #3 ; Brinf the numerstors to an equivalent value #4 ; Subtract the numertors #5 ; Place the numerstors over the denominator #6 ; brinf back to a mixed number. Hence #1 ; 2 4/5 - 14/5 = 14/5 - 13/15 #2 ; 3 x 5 = 15 . So common denomontor is '15' #3 ; Equivalent numerators are 14 x 3 = 42 ' 13 remains unchanged #4 ; 42 - 13 = 29 #5 ; 29/15 #6 ; 1 14/15 The answer !!!! NB THe process for addition of fractions is exactly the same , except at step #4 , where the numertors are added.
