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

Let's simplify this expression whilst making sure to follow the order of operations. Exponents precede multiplication and division, which in turn precede addition and subtraction, and that parentheses precede all of the above.

Therefore, we'll start by simplifying the expressions inside of the 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) given that this operation's result is not 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.
