Answer 1

The correct answer is: 1 .

_____

Step-by-step explanation:

When the number 4 is decreased by 75% , what is the result?

4 decreased by {75% of 4} ; what is that value?

First, what is 75% of _____ ; then

Second, subtract that value from 4 ; to obtain that result;

which is our answer.

75 % of 4 = (75/100) *4

Multiply each side to get rid of the fraction;

`(75)/(100) * (4)/(1)` ;

Now, cross-factor ;

100 / 4 = 25 ; Cross out the 100 and change 100 to 25 ;

and cross out the 4 and change to 1 ;

We now can rewrite the expression as:

`(75)/(25) *(1)/(1)` ;

Now we have:

`(75)/(25)` ; which is the same value as:

{75 ÷ 25) ; which equals 3 ;
Now we subtract this value, 3 , from the number, 4 ;

as per our original question/problem:
Hope this is helpful to you!
