Change the mixed numbers into simple fractions:
-9/4-(-67/8)
Find the common denominator and subtract:
$\frac{(-9*8)-(-64*4)}{4*8} = \frac{196}{32}= \frac{49}{8} =6 \frac{1}{8}$

So your answer is H

Answer:

Luis traveled 11.82 km in total.

Step-by-step explanation:

<em>The statement should say</em>: To visit his grandmother, Luis takes a train 6.37 kilometers and a car 5.45 kilometers. How many kilometers is Luis's journey in total?

Hence, to find the total distance traveled by Luis we must add the distances of the train (6.37 km) and the car (5.45 km):

$d = d_{t} + d_{c} = 6.37 km + 5.45 km = 11.82 km$

Therefore, Luis traveled 11.82 km in total.

I hope it helps you!
