Evaluate 5214 ÷ 39 ​
Andreas93 [3]

Answer: 133\frac{9}{13} or \frac{1738}{13} or 133.7 (any three are correct)

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

<h2><u>Problem:</u> Evaluate 5214 ÷ 39</h2>

<u>Step 1:</u> <em>5214 / 39 = 133 with a remainder of 27.</em>

133 with a remainder of 27

Because 39 is what we will be dividing it by, it will be our denominator.

<u>Step 2:</u> <em>Express as a mixed fraction.</em>

133\frac{27}{39}

<u>Step 3:</u> <em>Simplify by dividing the denominator/numerator by 3.</em>

133\frac{9}{13} or \frac{1738}{13} or 133.7

~I hope I helped you! :)~
