Question

What is the value of the expression? 6.4−2.4÷0.1 Enter your answer in the box as a decimal.

Answer 1

Answer:

The value of the expression is -17.6

Step-by-step explanation:

PEMDAS is the abbreviation for Parentheses, Exponents, Multiplication-Division, Addition-Subtraction. This is an abbreviation that establishes a standard order of operations for calculations that involve more than one arithmetic operation.

This indicates that any calculation is first due within the parentheses. The exponents are still important (powers and roots). Multiplication and division are equally important and must be resolved in order from left to right, as they appear. Finally, the addition and subtraction are equally important and must also be resolved in order from left to right.

Then, according to PEMDAS, the division must be done before the sum: 2.4÷0.1=24

So 6.4-2.4÷0.1= 6.4-24

Now, performing this subtraction you get -17.6

Answer 2

6.4−2.4÷0.1

According to PEMDAS

divide comes first in this problem

2.4 /.1 =24

6.4 - 24

-17.6
