Answer:
Our actual answer is 1/18 greater than our estimate
1/2 < 5/9
Step-by-step explanation:
5/8 is close to 1/2
8/9 is close to 1
1/2 * 1 = 1/2
Our estimate is 1/2
Actual answer
5/8 *8/9
Rewriting
5/9 * 8/8
5/9
How close
5/9 - 1/2
Getting a common denominator
5/9*2/2 - 1/8 *9/9
10/18 - 9/18
1/18
Our actual answer is 1/18 greater than our estimate
