Simple addition! I double checked!
Percent is a ratio where we compare numbers to 100 which means that 1% is 1 divide by 100
Answer:
Line up the decimal points. **Answer is Least to greatest: 10.5 , 11, 19**
Step-by-step explanation:
You need to line each number up.
10.5
11.0
19.0
The reason why 11 and 19 have a decimal point and zero at the end is because you need to do that in order to compare the numbers.
This problem is also a little common sense because 10.5 is the smallest, 19 is the largest while 11 is in the middle.
Cross multiply
10 x 9 = 90
3 x k = 3k
make an equality
90 = 3k
divide both sides by 3
90/3 = k
simplify
30 = k
