On the street where Jeffrey lives there area total of 10 houses. 7 of them are decorated with holiday lights. What percentage of the houses are decorated?

70% of the houses are decorated

Step-by-step explanation:

If you put 7 and 10 together into a fraction, it’s 7/10.

A Vinculum (the line between the denominater and numerator) is also a division sign, so you divide, 7/10 equals 0.7

Then you move the 7 up to the tenths place and get 70%.
