Lesson 5: Adding and subtracting mixed numbers

# Subtracting mixed numbers with like denominators

Sal practices subtracting mixed numbers with common (like) denominators.

• I understand the work, but I just don't know how to type it on the computer.
• To type a mixed number, you put the integer, a space, and then the fraction (use / to separate the numerator and denominator):

``  integer fraction  integer numerator/denominator  7 11/12  1 6/12``
• It is so hard to subtract fractions.😭
Can you explain to me how?
I can not understand.
Thanks!
• Its bascially like 5-1=4 but a fraction example is 3/4-1/4=2/4. Hope this helps :)
• Here's another way to subtract fractions easily:

Let's say, we have 8 2/3 - 5 1/3.
1. `Whole number - whole number`: 8-5=3.
That will determine the whole number in the final answer.
2. `Numerator - numerator`: 2-1=1.
That will determine the answer's numerator.
3. `Put it all together`: 3 + 1/3 ( Just carry over the starting denominator for the answer's denominator).

• If you write 6 5/12 as an improper fraction, would it be 77/12?

• You're absolutely correct my friend!

Step 1: 12 * 6 + 5 to get numerator
Step 2: Denominator remains the same.

In conclusion 6 5/12 becomes 77/12 as improper fraction. Cheers!
