The left-handed students12% are left handed, percent means per hundred. Change percent into per 100.
12% =
![\dfrac{12}{100}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B12%7D%7B100%7D%20)
Then simplify the fraction by dividing the numerator and denominator by 4
![\dfrac{12}{100}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B12%7D%7B100%7D%20)
=
![\dfrac{12:4}{100:4}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B12%3A4%7D%7B100%3A4%7D%20)
=
![\dfrac{3}{25}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B3%7D%7B25%7D%20)
This is the fraction showing the proportion of the left-handed students
The right-handed studentsDetermine the fraction showing the proportion of the right-handed students
1 - the left-handed
= 1 -
![\dfrac{3}{25}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B3%7D%7B25%7D%20)
Equalize the denominator to 25
![\dfrac{25}{25} - \dfrac{3}{25}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B25%7D%7B25%7D%20-%20%5Cdfrac%7B3%7D%7B25%7D%20)
Simplify
![\dfrac{21}{25}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B21%7D%7B25%7D%20)
This is the proportion of the right-handed students
<span>
Are there more right-handed or left-handed students?There are more right-handed students than the left-handed students, because 21/25 is more than 3/25</span>
Answer:
42
Step-by-step explanation:
Let x = the original number of bushes in garden A
Let x-9 = the original number of bushes in garden B
x-9-3=x-12 = bushes in garden B after transplanting 3
x+3 = bushes in garden A after transplanting 3
x+3=1.5(x-12)
x+3=1.5x-18
0.5x=21
x=42
There were 42 current bushes in garden A
