Answer:33/32
Step-by-step explanation:
81/4 - 615/32
32•4=128 to get a common denominator
Then whatever you do to the top you do to the bottom.
81•32=2,592
Then you would do
615•4=2,460
Now you have
2,592/128 - 2,460/128
Now you subtract
2,592-2460=132
You keep the denominator
132/128 and then simplify by dividing both numbers by four and you get
33/32
