Question

# [4-5{1-(4-3+1)}] of 100% equals a) 50% b)-1% c)zero d)100%

Answer 1

Answer:

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  =  $\frac{9}{100}$

              ⇒  9%
