Write the decimal number as a fraction
(over 1)
3.1818 = 3.1818 / 1
Multiplying by 1 to eliminate 4 decimal places
we multiply top and bottom by 4 10's
Numerator (N)
N = 3.1818 × 10 × 10 × 10 × 10 = 31818
Denominator (D)
D = 1 × 10 × 10 × 10 × 10 = 10000
N / D = 31818 / 10000
Simplifying your fraction
= 31818/10000
= 15909/5000
= 3 909/5000. Hope this helped!!!
The answer is 1 19/80 or 1.2375.
Hope this helps!
How I got the answer was simple, You solve for t by simplifying both sides of the equation, then isolating the variable.
The answer to this is t=-1
Answer:
Step-by-step explanation:
To calculate this you would first bring -14 over. In order to bring it over you would need to change the symbol from a minus to a plus, this cancels it out on the left but brings it over on the right. Then you are left with so you would divide it by 4 to find what e is equal to.
1) Bring the -14 over to the right.
Because we changed the symbol this cancels it out.
2) Then you would divide 24 by 4 to find out the answer for e.

Answer:
1. 80%
2. $44
3. 58.25
Step-by-step explanation:
If a book is 20% off then it will still have 80% that you have to pay for because the highest possible percentage is 100% and 100-20 is 80.
Percents can also be represented as decimals.
20% -> .20 80%->.80
There are two ways you can solve the next question.
55 - 55(.20) = 44
55(.80) = 44
If $46.60 is the sales price then it is .80 of the original price.
This can be written as an algebraic formula.
Let x be the unknown total price.
.80*x = 46.60
x = 46.60 ÷ (.80) = 58.25
You could also realize that .80=80/100=4/5. So divide 46.60 by 4 and multiply that by 5.
46.60÷4=11.65
11.65*5=58.25
