\[8\frac{ 1 }{ 2 }=\frac{ 8\times2+1 }{ 2 }=\frac{ 17 }{ 2}\] \[\frac{ 17 }{ 2 \times100 }\times 21000=17\times105=1785\]

please explain the way how you calcule it

Ava1:

\[\frac{ x }{ 21000 } = \frac{ 8.5 }{ 100 }\] Plug in a number for x which is \[1785\] \[\frac{ 1785 }{ 21000 }= \frac{ ? }{ 100 }\] Plug in 8.5 \[17/2 \] So therefore, 1785 should be your final answer. Credits: @joe348
