<u>Answer:</u>
To solve this, we need to first evaluate the given expression. We can do that by simplifying the contents of each bracket, starting with the innermost one:
[4-5{1-(4-3+1)}]
⇒ [4 - 5{1 - (2)}]
⇒ [4 - 5{-1}]
⇒ 4 - (-5)
⇒ 4 + 5
⇒ 9
Now we can calculate what 9 out of 100 is:
9 of 100 =
⇒ 9%
Answer:
It'll take a bucket loads of to empty world's ocean
Step-by-step explanation:
Given
To get the number of bucket loads, we simply divide the size of the ocean by the size of the bucket;
Expand the numerator
Recall that
So, the expression becomes
Simplify the numerator using laws of indices
Expand the denominator
Split fraction
Simplify fraction using laws of indices
Hence, it'll take a bucket loads of to empty world's ocean
