Answer:
3/10 of the aquarium are yellow tangs.
Step-by-step explanation:
Given that in an aquarium 2/5 of the fish or surgeonfish and of these, 3/4 are yellow tangs, to determine what fraction of all fish in the aquarium are yellow tangs the following calculation must be performed:
2/5 = 0.40
0.40 x 3/4 = X
1.20 / 4 = X
0.30 = X
0.30 = 3/10
Therefore 3/10 of the aquarium are yellow tangs.

Answer:
45%
Step-by-step explanation:
To solve this, we can turn it into a fraction. 18/40. If we are trying to determine what percentage he spent on fruit out of the money he spent at the grocery store, then we will divide the denominator (40) by the numerator (18). 18 divided by 40 is 0.45. Next, we multiply 0.45 by 100, which leaves us with 45%. Justin spent 45% on the fruit.
