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>Problem: Evaluate 5214 ÷ 39</h2>

Step 1: 5214 / 39 = 133 with a remainder of 27.

133 with a remainder of 27

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

Step 2: Express as a mixed fraction.

$133\frac{27}{39}$

Step 3: Simplify by dividing the denominator/numerator by 3.

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