Misleading wording in level 23

Line 1067 in e11f74c

    
           'en': '<p>Grid also introduces a new unit, the fractional <code>fr</code>. Each <code>fr</code> unit allocates one share of the available space. For example, if two elements are set to <code>1fr</code> and <code>3fr</code> respectively, the space is divided into 4 equal shares; the first element occupies 1/4 and the second element 3/4 of any leftover space.</p><p>Here, weeds make up the left 1/6 of your first row and carrots the remaining 5/6. Create two columns with these widths using <code>fr</code> units.</p>',

The explanation of fr is easy to misinterpret. Specifically this statement:

the first element occupies 1/4 and the second element 3/4 of any leftover space.

This leads me to believe that the first element will take up 1/4 of the available space and the second element will take up 9/16 of the available space (3/4 of the remaining 3/4).
