Answer:
12. C. 40 more students chose baseball than basketball
20. 500 total flowers
Step-by-step explanation:
12. To find the number of students that chose baseball, we multiply 25% by 800 students surveyed. First we have to convert 25% to a decimal = 0.25
800 x 0.25 = 200 students chose baseball.
Then, for basketball, 20% of students chose that, so 20% = 0.20
800 x 0.2 = 160 students chose basketball
200-160 = 40 more students chose baseball than basketball

20. I don't know what your "magic sentence" looks like. You can set this up as a ratio, where x is the total number of flowers, and the 56% is a fraction of 56/100
280/x = 56/100
then cross multiply
28,000 = 56x
divide by 56
x = 500
Check the math: 500 x 0.56 = 280
If you want to tell me what your teacher's "magic sentence" looks like in the comments, I can try to fill it in with/for you.
56/9
To get to the answer you flip the second fraction 1/8 to 8/1. Then multiply 7/9 x 8/1
