So,
This is simply subtraction.
26.2 - 18.5 = 7.7 mi.
This is exact.
However, if you wanted to round to the nearest mile, it would look like this:
26 - 19 = 7 mi.
This is because in 26.2 mi., 2 is less than 5, and in 18.5 mi., 5 is greater than or equal to 5.
This is rounding to the nearest mile.
136 would be the other measurement on a protractor.
Answer:
1/5
Explanation:
For every two minutes, 10 items get sold. 2/10 is equivalent to 1/5
For example, think about 8.4 - 2.9.
You have to regroup because you can't subract 4 - 9.
4 turns into a 14 since you borrow from the left number, 8.
8 turns into a 7 after that.
Now, you have to subtract 14 - 9 and 7 - 2. You're answer is 5.5.
You can check your work by doing inverse opperations:
By adding:
5.5 + 2.9 = 8.4
Or by subracting 8.4 - 5.5 = 2.9
Hope this helped you! If you need a better explaination or another example, I will be happy to help you! :)
