Question

What is the value of the expression? Drag and drop the answer into the box to match the expression. 0.9(1/2−2)+0.6

Answer 1

Answer:

The value of the expression $0.9 \cdot (\frac{1}{2}-2)+0.6$  is  -0.75.

Explanation:

Given: the expression $0.9 \cdot (\frac{1}{2}-2)+0.6$

BODMAS acronym is;

B - Bracket

O - Orders

D -Division

M - Multiplication

A - Addition

S - Subtraction  

Using BODMAS rule in the given expression, first solve the bracket terms;

$\frac{1}{2} -2 = \frac{1-4}{2} = \frac{-3}{2}$

Then we have;

$0.9 \cdot \frac{-3}{2} - 9$

next, multiply the terms 0.9 and $\frac{-3}{2}$ we get

$-1.35 +0.6$

then, Add the above numbers;

$-1.35 +0.6$ = -0.75

Therefore, the value of given expression is, -0.75

Answer 2

The answer would be: -0.75
I distributed the 0.9 to the .5 (I converted the fraction to a decimal) and the 2, afterwards I kept the parenthesis and subtracted the 0.45 with the positive 1.8 and I got -1.35. Then I added -1.35 to 0.6 and that's how I got -0.75 to be the solution.

I am probably wrong, but you could try doing PEMDAS after distributing the 0.9 to the .5 and 2.   :)
