Divide 4 and 5/8 by 5/8. you will get 7 and 2/5, or 7.4. since this you need whole pieces of wood, round down to 7.
final answer=7 pieces of wood
1+1/3+1/3 because 1/3 and 1/3 have the same denominator.
3 * 171 and you are going to get 513
(688-684) x 222

Then you have to multiply
4x222
=888
83-73 will make up to 155
