Please Help- <br> K + ⅓ = 5 ⅛ | K = ?<br> Show Your Reasoning.

blondinia [14]

Answer:

$4\frac{19}{24}$

Step-by-step explanation:

I hope I did this right:

So first thing to do is set up the equation.

$K + \frac{1}{3} = 5\frac{1}{8}$

Next thing to to is subtract 1/3 from both sides to get:

$K = 5\frac{1}{8} - \frac{1}{3}$

Next up, you will multiply each of the fractions by the opposing value

(multiply 1/8 by 3 and 1/3 by 8)

$K = 5\frac{3}{24}$ $-\frac{8}{24}$

Alright almost done, by multiplying 24 by 5 you get 120, that will go in the numerator to make the math a lot easier.

K = $\frac{123}{24}$ $-\frac{8}{24}$

Finally, you subtract 123 over 24 by 8 over 24.

K = $\frac{123}{24} - \frac{8}{24} = \frac{115}{24}$

Then just simplfy the 115/24 to get

$4\frac{19}{24}$
