Answer 1

The answer is: "40%" .
___________________________________________________
Step-by-step explanation:
___________________________________________________

2/5 = x/ 100 ; Solve for "x" ;

Looking at the denominators:

5*(what value) = 100 ? ; 100÷ 5 = 20 ;

So "5*20 = 100" .

So; "2/5 = (2*20)/(5*20) = 40/100 = 40% .

→ Since: 40% = 40/100 = 4/10 = (4÷2)/(10÷2) = 2/5 .

Alternate method:

2/5 = 2÷5 = 0.4 .

0.4 = 4/10 = =(4*10)/(10*10) = 40/100 = 40% .

Alternate method:

Given: "2/5" ; We look at the denominator and notice it is "5" ; and we known that "5*2" = 10" ;

So, "2/5" = (2*2)/ (5*2) = 4/10 = (4*10)/(10*10) = 40/100 = 40% .
