Answer:

Out of these 40 fish 32 are trout.

Explanation:

The ratio relationship for this is #8:10 -> t:40# where #t# is the number of trout. Turning this into an equation and solving for #t# gives:

#8/10 = t/40#

#40*8/10 = 40*t/40#

#320/10 = cancel(40)*t/cancel(40)#

#32 = t#

Answer:

32

Explanation:

40 is the fourth multiple of 10, which means that #10 xx 4 = 40#.

Then, if 8 out of 10 fish are trout, the number of trout in 40 fish will be the fourth multiple of 8, which is equal to #8 xx 4 = 32#.
