Two kinds of fish can be found in a small tank that is 5 feet long. a
blue fish is 2 2/15 foot long and an orange fish is 1 710 foot long. how much
longer is the orange fish?

Step-by-step explanation:

It is longer by = 2 2/15 - 1 7/10

= 32/15 - 17/10

= (64 - 51)/30

= 13/30 foot

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
