How do you turn a decimal into a fraction?

Answers

Answer 1

Answer: ok so remember
0.1=tenth=1/10
0.01=hundreth=1/100
0.001=thousantht=1/1000
and so on
you just count how many decimal places it is

example

0.3=3/10

0.04=4/1000

0.0343=343/10000

Answer 2

Answer: In order to turn a fraction into a decimal, you simply have to complete the fraction by dividing the numerator (the number on top of the fraction) by the denominator (the number on the bottom of the fraction).

For example, say we have the fraction $(1)/(5)$ . All we have to do to convert it into a decimal is divide 1 by 5.

1 / 5 = 0.2

So, the fraction $(1)/(5)$ written as a decimal would be 0.2.

x² – 6x= 5

Answers

Answer:

x = 8.7 or x = 1.3

Step-by-step explanation:

x² – 6x= 5

(b/2)² = (6/2)² = 9 (Using Completing the square method)

x² – 6x + 9 = 5 + 9

(x -5)² = 14

x-5 = √14

x-5 = ±3.7

Either x-5 =3.7 or x-5 = -3.7

x = 3.7+5 or x = -3.7+5

x = 8.7 or x = 1.3

Allie answered 72% of the questions on her math test correctly. If she answered 18 questions correctly, how many questions were on the test?

Answers

Answer:

25 questions

Step-by-step explanation:

The answer to this question can be solved by setting up a proportion, or equivalent ratios (fractions). Since we know that 18 questions was equal to 72% correct on the test, we can set up a proportion to find the total number of questions:

$(72)/(100)=(18)/(x)$ , where 'x' represents the total number of questions (or 100%) of the questions on the test.

Cross-multiply and divide: 72x = 18(100) or 72x = 1800

Divide both sides by 72: 72x/72 = 1800/72

Solve for x: x = 25 questions
