At brain's bookstore 0.3 of the shelves hold mystries, 25% of the shelfs hold travle books and 7/20 of the shelfs hold children books which type of book coners the most shelfs space in the store

We are given the amount of books in three different ways: a decimal, percentage, and fraction. If we express these values in the same format, they will be easy to compare.

0.3 is equal to 30 out of 100

25% is equal to 25 out of 100

Finally the numerator and denominator of 7/20 can both be multiplied by 5 to get 35 out of 100.

35 < 30 < 25, therefore children books take up the most space.
