How to convert improper fraction to mixed numbers

MakcuM [25]

Answer:

Step-by-step explanation:This is an improper fraction: 243/10 to convert it to a mixed number just do 243 divided by 10 which equals 24, so put that number as a whole number in front of the fraction, then do 24 times 10 which equals 240, then since 240 is 3 less than 243 the answer is 24 and 3/10.

If you need, I can try to explain it better.

What is the value of x in the equation 2(x+3)=4(x-1)

Nina [5.8K]

Firstly, expand the equation.
$2(x + 3) = 4(x - 1) \\ 2x + 6 = 4x - 4$

Next, move the variable x to the left and all the constant to the right.
$2x + 6 = 4x - 4 \\ 2x - 4x = - 4 - 6 \\ - 2x = - 10$

Then, solve for x.
$- 2x = - 10 \\ x = \frac{ - 10}{ - 2} \\ x = 5$
