Answer:
3 groups
Step-by-step explanation:
Sopranos = 12
Altos = 9
Find the highest common factor of 12 and 9
12 = 1, 2, 3, 4, 6, 12
9 = 1, 3, 9
The highest common factor of 12 and 9 is 3
Therefore, the choir teacher can only have 3 groups
12 sopranos / 3 groups
= 4 sopranos per group
9 Altos / 3 groups
= 3 altos per group
Each of the 3 groups Will have 4 sopranos and 3 altos each
The answer is 4+(9x1/10)+(5x1/1000)
Can i have a brainiest
This answer is not 3/4. The answer is 1/10. I found this by knowing that there are 10 numbers and there is a 1/10 chance that it will start with 7. I would really appreciate it if I could get brainliest. Thanks!! =D
B. the middle letter in the name of the angle is always the vertex

is our fraction, which is not in lowest form, and therefore can be reduced. We can divide both numerator and denominator by 2, and we end up with

7 goes into 14 twice, so we can reduce it further to become

To convert a fraction to a ratio, you just need to turn it on its side and make the | into a : So it would look like this:
1:21 / 2 = 0.5

0.5 is the fraction in decimal formTo find a percentage, you just need to multiply the decimal by 100.
0.5 in percentage form would be 50%
Hope that helped =)
