What Is 9-74+39/78+192-465?
-465.1354166666667
If your question mean:
9 - 74 + ( 39 / 78 ) + 192 - 465
then
39 / 78 = 1 / 2
9 - 74 + ( 39 / 78 ) + 192 - 465 = 9 - 74 + 1 / 2 + 192 - 465 =
- 338 + 1 / 2 = - 2 ∙ 338 / 2 = - 676 / 2 + 1 / 2 = - 675 / 2
If your question mean:
( 9 - 74 + 39 ) / ( 78 + 192 - 465 )
then
( 9 - 74 + 39 ) / ( 78 + 192 - 465 ) = - 26 / - 195 =
26 / 195 = 13 ∙ 2 / 13 ∙ 15 = 2 / 15
My typo:
9 - 74 + ( 39 / 78 ) + 192 - 465 = 9 - 74 + 1 / 2 + 192 - 465 =
- 338 + 1 / 2 = - 2 ∙ 338 / 2 + 1 / 2 = - 676 / 2 + 1 / 2 = - 675 / 2
To solve the expression 9-74+39/78+192-465, we need to follow the order of operations, which is often remembered using the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break down the expression step-by-step:
1. Start with addition and subtraction from left to right:
9 - 74 = -65
2. Next, perform the division operation:
39 ÷ 78 = 0.5
3. Continue with addition and subtraction:
-65 + 0.5 = -64.5
-64.5 + 192 = 127.5
127.5 - 465 = -337.5
Therefore, the answer to 9-74+39/78+192-465 is -337.5.
