. If in photo, the head size is 
% from all of the body (include three pieces) and te ratio of the size of body and foot is 
. Find the percentate of body size (just body) to all of his body(include three pieces) inthe real condition-
Because the head size is 15% then the total size of body and foot is: 100% - 15% = 85%
The percentage of body size is: \(\dfrac{85}{\left(5+7\right)}\cdot5=\dfrac{425}{12}\approx35\%\)
P/s: I can't understand of the ratio 1:10
