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?

Result

n =  2
r =  0.167 cm

Solution:

l1=1+23=53≐1.6667 cm l2=3/4=34=0.75 cm  n=l1/l2=1.6667/0.75≐209≐2.2222≐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 \doteq \dfrac{ 20 }{ 9 } \doteq 2.2222 \doteq 2
r=l1−n⋅ l2=1.6667−2.2222⋅ 0.75≐16≐0.1667≐0.167 cmr=l_{1} - n \cdot \ l_{2}=1.6667 - 2.2222 \cdot \ 0.75 \doteq \dfrac{ 1 }{ 6 } \doteq 0.1667 \doteq 0.167 \ \text{cm}
