10/2= 5 trees per hour.
150/5= 30
It would take 30 hours to plant 150 trees.
I hope this helps!

If the exponent of the 10^(A NUMBER) part is positive, then it is greater than one.
Answer:
808, 818, 909, 919
Step-by-step explanation:
Digits greater than 7 are 8 and 9.
Digits less than 2 are 0 and 1.
There are four (4) possible combinations of these digits: 80, 81, 90, 91. Since your numbers end the same way they start, there are 4 possibilities:
808, 818, 909, 919
Okay, so the top numbers are how many pieces we have, and the bottom number is how many pieces there are, think of it like a pizza. If the pizza is cut into 8 slices and you have one slice, you have a smaller piece of pizza than one slice from a pizza that was only cut into 6 pieces, which is smaller than one slice from a pizza that was only cut into 3 pieces. The more pieces there are, the smaller the pieces are, so the bigger the bottom number is, the smaller the fraction is.
