Answer:
2800
Step-by-step explanation:
Just round the 43 to 40 and the 68 to 70. So the problem then converts to 40x70 to get a rough estimate. 40x70=2800
Answer:
8 bags
Step-by-step explanation:
You divided them by 20 which gives you 4. So you take the 3 and multiply by 4 which is 12 bags. And then you do the same for your bags which makes you do 2 times 4 which gives you 8. You take 20 - 12 and that leaves you with 8.
The value is 0.02
If it is a negative number, you move the decimal over to the left. :)
