Answer:
Yes, -13 is less than f/2.
Step-by-step explanation:
Since we are given a fraction with a variable, it may seem hard at first to find out which number is greater.
First, we have to realise that -13 is a negative number. Any negative number is always equal to less than a positive number.
Whatever number we replace our variable f with, whether it be 2, 3, 9, or 0.00000000000001, we can rest assure that it will be a <em>positive</em> number.
Since positive numbers are greater than negative ones, -13 has to be less than f/2.
If the fraction was negative (- f/2), this would be a nearly impossible question to answer.
Hi there!
We can set up a ratio to model the problem...
540/3000 = x/100
Now, just cross multiply and solve for x.
54000 = 3000x
x = 18
Therefore, 18 percent of last semester's college costs was spent on books. Hope this helped and have a great day!
