To change a fraction to a decimal , you just divide the number on top by the number on the bottom.
So to change 3/11 to a decimal you divide 3 by 11 and you get 0.272727
= 3/11
= 3 ÷ 11
<span>= 0.272727

you can round this to 0.273
Answer:
8/21
Step-by-step explanation:
The total job is 1
Mike has done 1/3 and Dena has done 2/7 of the job We still need to do x of the job to complete it
1/3 + 2/7+ x = 1
We need to get a common denominator 3*7 = 21
Multiply each side by 21
21(1/3 + 2/7+ x) = 1*21
21(1/3) + 21*(2/7)+ 21x = 21
7+ 3*2 +21x =21
7+6+21x = 21
13+21x = 21
Subtract 13 from each side
13-13+21x=21-13
21x = 8
Divide each side by 21
21x/21 = 8/21
x = 8/21
We need to complete 8/21 of the job
<h3>
Step-by-step explanation:</h3><h3>(2/3)x - 2 = 7</h3>
(2/3)x = 7 + 2
(2/3)x = 9
2x = 9 × 3
x = 27/2
:. x = 13 1/2
Answer:
1/36
Step-by-step explanation:
The probability that the first winner lives in Gaston is 2/9. The probability that the second winner lives in Gaston is 1/8, the number of remaining Gastonites divided by the total number remaining in the pool.
Then the probability of both of these events is the product:
P(2 from Gaston) = (2/9)(1/8) = 2/72 = 1/36
The probability both are from Gaston is 1/36.
Answer:
B -1/9
Step-by-step explanation:
(y - 1) / y = 10
y - 1 = 10y
- 1 = 9y
y = -1/9
