Question

p=2,25'+3,75'-15 27/32''

Answer 1

P = 2,25´ + 3,75´ - 15 27/32" 
P = 2,25*60" + 3,75*60 - (15*32 + 27)/32 " 
P = 135" + 225" - 507/32 " 
P = ((360*32 - 507)/32)" 
P = ((11 013)/32)" 
P = 334,16" 

P = (10688 + 325)/32" 
P = 10688/32" + 325/32" 
P = 334" + 325/32" 
P = 5*60" + 34" + 325/32" 
P = 5*60" + (34 + 325/32)" 
P = 5´+ 1413/32" 
P = 5`(1413/32)" 

P = 5´44,16"
