Solve Sequential Division: (4+7+3):2:3 Step-by-Step

Let's simplify this expression while following the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses come before all of them,

Therefore, we'll start by simplifying the expressions in parentheses first:
$(4+7+3):2:3= \\ 14:2:3$

We'll continue and calculate the result of the expression obtained in the last stage, step by step from left to right (which is the regular order of arithmetic operations):

$14:2:3 =\\ 7:3 =\\ \frac{7}{3}=\\ 2\frac{1}{3}$

In the second stage where we performed the last division operation, we wrote the result as an improper fraction (a fraction where the numerator is greater than the denominator) because this operation's result doesn't give a whole number. Later, we converted it to a mixed number by finding the whole numbers and adding the remainder divided by the divisor (3),

Therefore, the correct answer is answer A.
