Arturo has a log that is 4 yards long. he cuts the log into pieces that are 1/3 yard long . how many pieces will Arturo have?

1 answer:

8 0

Arturo will have 12 pieces. For this problem, you need to multiply by the reciprocal. To do that, you flip 1/3 over to 3/1 and multiply that by 4. 3/1 times 4 equals 12. Remember that 4 as a fraction is 4 over 1. So you would multiply 4 by the numerator (3) because 4 is the numerator in 4/1.

Answer:

The results don't make sense

Step-by-step explanation:

We can solve by means of a 2x2 system of equations, we have to:

"x" is the number of children's tickets

"y" is the number of adult tickets

Thus:

8 * x + 8.75 * y = 259

x + y = 35 => x = 35 - y

replacing we have:

8 * (35 - y) + 8.75 * y = 259

280 - 8 * y + 8.75 * y = 259

- 8 * y + 8.75 * y = 259 - 280

0.75 * y = -21

y = -21 / 0.75

y = -28

Thus:

x = 35 - (-28) = 63

With these results we notice that the problem has inconsistency, since the value of the tickets cannot be given a negative number, I recommend reviewing the problem, since the approach is correct.
