Answer:
5'4"
Explanation:
In terms of height, the apostrophe ( ' ) stands for feet and the quotation mark ( " ) stands for inches.
Your first term includes 4 feet and 9 inches. There are 12 inches in a foot, so we can simplify this as being 57 (48+9) inches.
Your second term includes 7 inches.
Add your two terms (57 and 7) together, and you have 64 inches.
Again, there are 12 inches in a foot, so to convert 64 inches to feet, count how many times you can put 12 into 64 without surpassing 64.
12 / 24 / 36 / 48 / 60
This will result in 5 times, so you have 5 feet and 4 inches left over.
