Question

A piece of wood that is 3/4 meter long is being cut into smaller pieces that are each 1/10 meter long.Which equation could be solved as the first step to find the number of pieces,n, that can be made?

Answer 1

Since the smaller pieces are all equal.

Then, X1=X2=X3...=1/10.

Therefore, the sum of the whole pieces should give you 3/4 back.

X1+X2+X3...=3/4

Therefore, (3/4÷n)=1/10

where n is the number of all the pieces.

I hope this helps
