Answer: 15/4 or 3 3/4
Step-by-step explanation: To figure out the area we do the equation, Length x Width so... 1 1/4 x 3
You cannot multiply mixed numbers so we turn that into an improper fraction. The improper fraction for 1 1/4 is 5/4
You also cannot multiply whole numbers with fractions so you turn that into a fraction too. The fraction for 3 is 3/1.
The final equation is 5/4 x 3/1 = 15/4
Now you need to change it into a mixed number. The mixed number of 15/4 is 3 3/4
