From the question, we are informed that it takes 12 buckets of water to fill a fish tank. We are further told that Chloe uses scoops which are equal to 1/4 of a bucket.
The number of scoops that are needed to fill the whole tank would be:
= 12 ÷ 1/4
= 12 × 4
= 48
30+4X=90 (right angle is 90°)
X=15
4 (15)= 60
30+60= 90 so you know it's right
