2+2-1 that's three quick maths.
If you divide decimals you have to bring up the decimal point but if you divide whole numbers you dont have any decimal points so you just divide the numbers. Sorry if i didnt help i just wanted to help.
Answer:
C
Step-by-step explanation:
![\rm \looparrowright - \frac{1}{4} (8 - 4 + 20x)](https://tex.z-dn.net/?f=%20%5Crm%20%5Clooparrowright%20-%20%20%5Cfrac%7B1%7D%7B4%7D%20%288%20-%204%20%2B%2020x%29)
Subtract the numbers
![\rm \looparrowright - \frac{1}{4} (4+ 20x)](https://tex.z-dn.net/?f=%20%5Crm%20%5Clooparrowright%20-%20%20%5Cfrac%7B1%7D%7B4%7D%20%284%2B%2020x%29)
Factor out 4 from the expression
![\rm \looparrowright - \frac{1}{ \cancel4} \times \cancel4(1 + 5x)](https://tex.z-dn.net/?f=%20%5Crm%20%5Clooparrowright%20%20%20-%20%5Cfrac%7B1%7D%7B%20%5Ccancel4%7D%20%20%5Ctimes%20%20%5Ccancel4%281%20%2B%205x%29)
![\rm \looparrowright - (1 + 5x)](https://tex.z-dn.net/?f=%20%5Crm%20%5Clooparrowright%20%20%20-%20%281%20%2B%205x%29)
When there is a - in front of an expression in parentheses, change the sign of each term in the expression to -
![\rm \looparrowright - 1 - 5x](https://tex.z-dn.net/?f=%20%5Crm%20%5Clooparrowright%20%20%20-%201%20%20-%20%205x)
- <em>Thus, Options A and F are correct!!~</em>
Find a common denominator by multiplying the denominators together. Use that common denominator to create equivalent fractions. Then, compare the numerators to figure out which is bigger
