How can I get the answer:

9 / 3.8 - 2.3
I don't know if I need to divided first or get the difference.
Thank you for helping me.

9 / 3.8 - 2.3 =

9 / 3.8 - ( 2.3 * 3.8 ) / 3.8 =

( 9 - 2.3 * 3.8 ) / 3.8 =

( 9 - 8.74 ) / 3.8 =

0.26 / 3.8 ( Multiply both sides with 100 =

= 26 / 380 =

(2 * 13 ) / ( 2 * 190 ) =

13 / 190

9 / 3.8 - 2.3 = 13 / 190

just follow MDAS: Multiplication, Division, Addition Subtraction. this is the sequence that should be followed when there are multiple operations.

however, for operations involving only Multiplication and Division, you can solve them left to right. for example,
6 / 3 * 4
2 * 4 = 8
also, for operations involving only Addition and Subtraction, you can solve them as is. for example,
5 - 7 + 3
-2 + 3 = 1

in the problem, the operations involved are division and subtraction. Thus we solve this by doing division first, then subtraction. just use a calculator:
9 / 3.8 - 2.3
2.368 - 2.3 = 0.068

hope this helps~ :)

To get the answer to the expression 9 / 3.8 - 2.3, we follow the order of operations, also known as "PEMDAS."

P stands for Parentheses - If there were any parentheses in the expression, we would simplify the expression inside them first. However, there are no parentheses in this case.

E stands for Exponents - If there were any exponentiation operations, we would perform them next. But again, there are no exponents here.

M and D stand for Multiplication and Division - In this case, we have division (9 / 3.8). So, we need to perform this division first. Divide 9 by 3.8 to get the quotient.

A and S stand for Addition and Subtraction - Finally, we have subtraction (-(2.3)). After performing the division in the previous step, subtract 2.3 from the quotient obtained.

Therefore, the step-by-step process to find the answer would be:

1. Calculate the division: 9 ÷ 3.8 = 2.36842105263 (keep this value for the next step).
2. Subtract 2.3 from the result obtained in step 1: 2.36842105263 - 2.3 = 0.06842105263.

So, the final answer is approximately 0.06842105263.
