How do you subtract mixed fractions?

1 answer:

5 0

Make it an improper fraction by multiplying the whole number by the denominator then adding the numerator then find the common denominator (remember what you do to the bottom, you do to the top) then subtract normally.

eg. 1 4/5 - 1 7/10

= 9/5 - 17/10

= 18/10 - 17/10

= 1/10 or 0.1

Hope this helps!

Answer:

$\huge \boxed{x=-11}$

Step-by-step explanation:

First, divide by 2 from both sides of equation.

$\displaystyle \frac{2(x+6)}{2}=\frac{-10}{2}$

Then, solve.

$\displaystyle x+6=-5$

Subtract by 6 from both sides of equation.

$\displaystyle x+6-6=-5-6$

Solve to find the answer.

When painting my bedroom I used 3 1/2 liters of blue paint and 2 1/4 liters of red paint. How much paint did I use in all

Lubov Fominskaja [6]

Hi there!

To solve this problem, we need to find the total amount of paint used by adding the two fractions.

First, we need to find the common denominators below adding.

1/2 = 2/4
1/4 = 1/4

The common denominator is 4.

Now, we add the mixed numbers together:

3 2/4 + 2 1/4 = 5 3/4

Since 5 3/4 can't be simplified, the answer is:

5 3/4 liters of paint

Hope this helps!
