You can convert each improper fraction to a mixed number, or vice versa to answer this.
I started by looking at the fractions with 4 in the denominator, since there are two mixed numbers with 4 in the denominator. Below we show the conversions of all of the mixed numbers.
To convert a mixed number to an improper fraction, multiply the integer by the denominator and add the numerator. Express the total over the denominator:
So, you have ...
The appropriate choice is ...
13/4 = 3 1/4
_____
You can also convert the improper fractions to mixed numbers. Divide the numerator by the denominator. The result is an integer and a remainder. The remainder is expressed over the divisor as a fraction:
angles are formed.
Answer:
Two sets of vertical angles are formed.
