Step [tex] 1 [/tex]
Find the sum of red clay and yellow clay
we know that
[tex] 1\frac{1}{2} =\frac{2*1+1}{2} = \frac{3}{2} [/tex]
so
[tex] \frac{3}{2} +\frac{3}{4} =\frac{(2*3+3)}{4} =\frac{9}{4} \ pound\ of \ clay\ mixture [/tex]
Step [tex] 2 [/tex]
Divide the total pound of clay mixture by [tex] \frac{1}{8} [/tex]
so
[tex] \frac{\frac{9}{4}}{\frac{1}{8}} =\frac{72}{4} = 18\ students [/tex]
therefore
the answer is
The total of students is [tex] 18 [/tex]
