What is 2/9 turned into a decimal?
2 answers:
Step-by-step explanation: To write 2/9 as a decimal, we begin by dividing 9 into 2.
Since 9 doesn't divide into 2, we write a decimal point and a zero after the 2 so that we can divide 9 into 20.
9 divided into 20 two times . so we write a 2 in our answer above the zero. 2 multiplied by 9 is 18 and 20 - 18 is 2.
Now, we write another zero under the division sign and bring down the zero so we have 20. Again, 9 divides into 20 two times, 2 x 9 is 18, and 20 - 28 is 2.
Notice that there seems to be a pattern forming. To make sure that this is true, we write another zero under the division sign and bring down the zero so we have 20. 9 divided into 20 two times, 2 x 9 is 18, and 20 - 18 is 2.
Our decimal does not seem to be ending and our same digit is repeating.
Therefore, 2/9 converted into a decimal is 0.2 repeating.

Answer:
3/4
Step-by-step explanation:
You can do this two different ways. Both include picking two points where the line crosses a corner. I'm using (0,-1) and (4,2). Now here you can either use
Slope=
or
If you use the first one start at point (0,-1) and go to point (4,2) and count how many it goes up (rise) and then put that over how many it goes to the right (run).
If you use the second one then plug in the numbers.
y2=second y point
y1=first y point
x2=second x point
x1=first x point
Now just solve.
