2.125 = 17/8 = 21/8 as a fraction
Step by Step Solution
To convert the decimal 2.125 to a fraction follow these steps:
Step 1: Write down the number as a fraction of one:
2.125 = 2.125/1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 3 numbers after the decimal point, we multiply both numerator and denominator by 1000. So,
2.125/1 = (2.125 x 1000)/(1 x 1000) = 2125/1000.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(2125,1000) = 125. So,
(2125÷125)/(1000÷125) = 17/8 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 2125/1000 is also equal to 2 1/8 when expressed as a mixed number.

Answer:
1.)-8
2.)-5
3.)4
Step-by-step explanation:
So, the function f(x)=3x-5
The questions say "If you were to substitute these numbers what answer would you get?"
Understanding this,
First question is with x=-1
f(-1)=3(-1)-5
f(-1)=-3-5=-8
_____________________________________
f(0)=3(0)-5
f(0)=0-5=-5
_____________________________________
f(3)=3(3)-5
f(3)=9-5=4
0 is the starting pointing for equations that are for positive numbers. 0 sets an easy way to figure out problems that have negatives. 0 is important to solve any problem with integers, and decimals!
