Answer:
Step-by-step explanation:
1 19/20 meters
5 3/4 - 3 4/5
We need a common denominator of 20
5 3/4 *5/5 = 5 15/20
3 4/5 *4/4 = 3 16/20
5 15/ 20 - 3 16/20
We will have to borrow 1 from the 5 in the form of 20/20
4 + 20/20 +15/20 - 3 16/20
4 35/20 - 3 16/20
1 19/20
54
Well, divide 300 by 100, which gets you 3. So 3 feet of book shelves = 1%
So 3x18=54
