How do you subtract a mixed number by a mixed number?

Answer 1

Here is an example

2 4/5 - 1 2/3

Steps to take

#1 ; Convert to improper (top heavy) fractions

#2 ; Bring to a common denominator

#3 ; Bring the numerators (top) to equivalent values

#4 ; Subtract the numertors

#5 ; Place over the denomiator

#6 ; Brinf back to a mixed numbers.

So taking these steps

#1 ; 2 4/5 - 1 2/3 = 14/5 - 5/3

#2 ; 5 X 3 = 15

#3 ; 14(3) = 42 & 5(5) = 25

#4 ; 42 - 25 = 17

#5 ; 17/15

#6 ; 17/15 = 1 2/15 The Answer!!!!!

NB Addition of mixed numbers is exactly the same except step '4' , where you add the numerators.

e.g. 2 4/5 +1 2/3

#1 ; 2 4/5 + 1 2/3 = 14/5 + 5/3

#2 ; 5 X 3 = 15

#3 ; 14(3) = 42 & 5(5) = 25

#4 ; 42 + 25 = 67

#5 ; 67/15

#6 ; 67/15 = 4 7/15 The Answer!!!!!

To subtract a mixed number by a mixed number you first need to turn the fractions into improper fractions then you just subtract them as you would with the normal fractions
