# siblings ratio fraction decimal percent
- 0 3 : 20 3/20 .15 15%
- 1 1 : 5 1/5 .20 20%
- 2 3 : 8 3/8 .375 37.5%
- 3 6 : 25 6/25 0.24 24%
- 4+ 7 : 200 7/200 0.035 3.5%
Step-by-step explanation:
I'll use row 3 as an example to show you how to do all these.
# siblings ratio fraction decimal percent
- 3 <u> </u> <u> </u> 0.24 <u> </u>
<u>To find fraction</u>
put number over 100 and just simplify as much as you can.
24/100 = 12/50 = 6/25
<u>To find ratio</u>
ratios are the same as fractions, but instead of the fraction bar or slash, you have a colon.
this one would look like 6 : 25 as a ratio.
<u>To find decimal</u>
DIVIDE the fraction or ratio (using a calculator if allowed, or by hand otherwise)
6/25 = 0.24
<u>To find percent</u>
take the decimal once you find it, and move the decimal point to the right by 2 digits. That's the percent.
0.24 ==> 24%
Answer:
Option (4)
Step-by-step explanation:
By applying triangle sum theorem in ΔABC,
m∠A + m∠B + m∠C = 180°
80° + 40° + m∠C = 180°
m∠C = 180° - 120°
m∠C = 60°
Since, ∠ACB ≅ ∠DCE [Vertically opposite angles]
m∠DCE = m∠ACB = 60°
Now by applying triangle sum theorem in ΔCDE,
m∠DCE + m∠CED + m∠CED = 180°
60° + 70° + x° = 180°
x = 180 - 130
x = 50°
Therefore, Option (4) will be the answer.
The probability that the student, who was chosen at random, was female and got an "A' on the test is <u>0.1645</u>.
<h3>What is probability?</h3>
Probability is the measurement of the likelihood of an event occurring.
The probability that an event occurs can be equal to or less than 1.
<h3>Data and Calculations:</h3>
Grades A B C Total
Male 18 4 17 39
Female 8 3 20 31
Total 26 7 37 70
Probability of being Female and getting an "A" = 0.1645 (31/70 x 26/70)
The probability of being female = 31/70
The probability of getting an "A" = 26/70
Thus, the probability is <u>0.1645</u>.
