Well I don't know !
Let's get together and figure it out:

The product of ' A ' and ' B ' is (A B) .

If you decrease ' A ' by 25%, then ' A ' becomes ' 0.75 A ' .

If you decrease ' B ' by 50%, then ' B ' becomes ' 0.5 B ' .

Now their product is (0.75 A) x (0.5 B) .

In multiplication, the order of the factors doesn't matter.
So we car re-arrange the new product as

   (0.75 x 0.5) x (A B) .

But (A B) is the original product, before we started
messing around with ' A ' and ' B '.

So the original product has become

   (0.75 x 0.5) = 0.375 of itself .

The original product has been reduced by

   (1 - 0.375) = 0.625 of itself.

How to solve this problem

Mamont248 [21]

To solve this you start off with the innermost parenthesis, which would be (4.1 + 1.8)
which leaves you with the last pair of parenthesis or brackets [ 7.9-5.9].
This is solved and you are left with 2.
Exponents are next in the line and you are left with 0.2 to the second power divided by 2. You are then left with 0.20.
Simply fill in these answers in the boxes and you have your answers.
