Acarpenter used 9 1/2 ft of cedar for every 7 2/3 ft of redwood for a construction project. if the carpenter uses 4 3/4 ft of cedar, how much redwood does he need?

For this case we can solve the problem by making the following rule of three:

9 1/2 ft of cedar --------------> 7 2/3 ft of redwood

4 3/4 ft of cedar --------------> x

From here, we clear the value of x.

We have then:

Rewriting the expression we have:

The carpenter needs the following amount of redwood:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

your answer is the frist one
