Question

Valeria tried to evaluate an expression. Here is her work: 8+12÷442 = 8+12÷416 Step 1 = 20÷416 Step 2 = 516 Step 3 = 80 Step 4 Is Valeria's work correct?

Answer 1

Answer:

Valerie's work is incorrect

Step-by-step explanation:

We solve the above question using the order of PEDMAS

P = Parentheses

E = Exponents

D = Division

M = Multiplication

A = Addition

S = Subtraction

Valeria tried to evaluate an expression. Here is her work:

= 8+12÷416

Let's solve this

From PEDMAS above, Division comes before Addition.

Hence:

Step 1: Division

8 + (12 ÷ 416)

Step 2: Addition

Hence, Valerie's work is incorrect
