Answer:
two the right then below
Step-by-step explanation:
7 1/5:
Multiply the denominator and the whole number: 7*5 = 35 and then add the numerator: 35+1= 36/5. Then, do this for the following fraction, the improper fraction value of 2 2/15 is 32/15.
Now we need 36/5 & 32/15 to have common denominators so that we can simplify it a little less complicated.
For Instance,
36/5*3= 108/15
Now we divide, (108/15)/(32/15)
108/32= 3.375 = 3 3/8
Answer is 3 3/8.
Hope this was easy to understand!
