Chester

Chester has a piece of wood measuring 1 2/3 cm he needs to cut it to pieces measuring 3/4 cm long. How many pieces of wood did Chester cut?

Correct result:

n =  2
r =  0.167 cm

Solution:

l1=1+23=531.6667 cm l2=3/4=34=0.75 cm  n=l1/l2=1.6667/0.75=209=2l_{1}=1 + \dfrac{ 2 }{ 3 }=\dfrac{ 5 }{ 3 } \doteq 1.6667 \ \text{cm} \ \\ l_{2}=3/4=\dfrac{ 3 }{ 4 }=0.75 \ \text{cm} \ \\ \ \\ n=l_{1}/l_{2}=1.6667/0.75=\dfrac{ 20 }{ 9 }=2
r=l1n l2=1.66672.2222 0.75=16=0.167 cmr=l_{1} - n \cdot \ l_{2}=1.6667 - 2.2222 \cdot \ 0.75=\dfrac{ 1 }{ 6 }=0.167 \ \text{cm}
