A would be 6/12 (1/2) and B would be 1/12. To make this easier to understand, think of it this way. 6+1=7, and 6-1=5. In the future, find what adds to 7 and begin plugging in numbers until you get the correct answer.
X = number of flower choices
We have 4 times of trees and 6 kinds of shrubs and x kinds of flowers
Overall, we'll have 4*6*x = 24*x different ways to pick three items (one per type).
Set this expression equal to 168 and solve for x
24*x = 168
24*x/24 = 168/24
x = 7
Answer: B) 7
It would be 20 because if you estimate 53 you would get 50 so 50÷3 would be clase to 2 and then add 1 zero and you will get 20 so 20 is your answer. Hope this helped. ☺
Because you follow wherever the evidence leads you.
