How to solve 2×4÷3+5

Nataly [62]

You will need to follow order of operations, which states that operations must be completed in the following order: parentheses, exponents, multiplication and division, and then addition and subtraction.

In this case, there are no parentheses and no exponents, so we will start with the multiplication and division:

$2 \cdot 4 \div 3 + 5 = (2 \cdot 4 \div 3) + 5$

$\Bigg(\dfrac{8}{3} \Bigg) + 5$

Now, we will finish by doing addition and subtraction:

$\Bigg(\dfrac{8}{3} \Bigg) + 5 = \dfrac{8}{3} + \dfrac{15}{3}$

$\dfrac{8 + 15}{3}$

$\boxed{\dfrac{23}{3}}$

Our answer is $\boxed{\dfrac{23}{3}}$ .
