Step-by-step explanation:
In this question we need to decrease 216 by [tex]37\dfrac{1}{2}\%[/tex] or 37.5 %.
For this, firstly find 37.5 % of 216.
[tex]37.5\%\ \text{of}\ 216=\dfrac{37.5}{100}\times 216\\\\=81[/tex]
Now subtracting 81 from 216 to find decrease of 216 by 37.5 %.
So,
216-81 = 135
Hence, 135 is the decrease of 216 by 37.5 %.
