1. a 

2. 6 tps baking powder. For every 3, there is two. 3 multiplied by 2 is 6.

3. 12/8 = 1.5 seedling per minute in 70 minutes...
1.5 * 70 = 105 seedlings can be planted in 70 minutes

4. idk sorry

5. time = distance / speed
time = 300/15
time = 20 hrs


7. The ratio between 12 and 8 is 1.5, so you need to divide every other number by 1.5.
2/1.5=1.3

9/1.5=6

18/1.5=12

8. So, problem statement tells you that 1lb = 16oz and that 1oz = 28.3g. That means that 1lb = 16 * 28.3g = 452.8g

You have three items, convert their weights to grams:
1) 800g
2) 1.6lb = 1.6 * 452.8g = 724.48g
3) 30oz = 30 * 28.3g = 849g

So, sorting from greatest:
3, 2, 1, or: 30oz, 1.6lb, 800g.

9. 5•7=30

10.it will clean 7 cars in 56 minutes
hope this helps and i hope its not confusing

grandymaker [24]
First you add 3/4 and 2/3 you but then do 3/4 2/3 you think what the both can go to is 12 the dominator is 12 then you time it by 3,4 because they both go to 12 then the 3 will be time 3 because 4 x 3 = 12 then you do it the top so 3x3 = 9 9/12 then you do the next one is2/3 do the same then will get 8/12 then you can subtract it 9/12 - 8/12 will gave you 1/12
