So,

For every 2 large notebooks Ann orders, she orders 1 small notebook.

This can be stated as a ratio: 2:1

Add up the units to find the value of each unit.
2 + 1 = 3
Divide 48 by 3 to get the unit value.
48/3 = 16

The unit value is 16.

The number of large notebooks Ann orders is 2(16):16
This is a 2:1 ratio.

Therefore, Ann ordered 32 large notebooks and 16 small notebooks.
