Hello There!
You want to know how long will it take Tammy to ride her bike 8 miles.

[Firstly, divide 45 with 5.]
0 9
-----------
5 | 4 5
- 0
--------
4 5
- 4 5
--------------
0
45 ÷ 5 ≈ 9
[Secondly, multiply 9 with 8]
You can do the 9 trick.
* Put up 10 fingers in the air
* Put the 8th finger down
* Count whats in the left and then the right.
7 in the left 2 in the right.
So, 9 × 8 = 72
Therefore, it takes 72 minuets for Tammy to ride 8 miles.
Hope this helped!
