(3×5+5):(4+3×2)= (3\times5+5):(4+3\times2)=

Video Solution

Solution Steps

00:00 Solve the following expression
00:03 Always solve the parentheses first
00:08 Multiplication and division precede addition and subtraction
00:35 Continue calculating all the parentheses and only then divide
00:43 This is the solution

Step-by-Step Solution

Use the order of operations to simplify the given operation. The order of operations states that exponents precede multiplication and division, which precede addition and subtraction, and that parentheses precede all of the above:

In the given expression, there is a division operation between two expressions inside of parentheses. Therefore we will first simplify these expressions (due to the fact that they are inside of parentheses)

We will simplify the expressions simultaneously, whilst following the aforementioned order of operations. Given that multiplication precedes addition, we will begin by calculating the results of the multiplications operations and then proceed to perform the addition:

(35+5):(4+32)=(15+5):(4+6)=20:10=2 (3\cdot5+5):(4+3\cdot2)= \\ (15+5):(4+6)=\\ 20:10=\\ 2

In the final step, we perform the remaining division operation (located between the parentheses in the original expression).

Therefore, the correct answer is answer C.
