Explanation:
_______________
Method 1)
______________________________
5/8 * 2 = 5/8 * 2/1 = (5*2)/(8*1) = 10/8 = (10÷2)/(8÷2) = 5/4 = 1¼ = 1.25 .
_______________________________
Method 2).
______________________________
5/8 * 2 = 5/8 + 5/8 = (5+5)/8 = 10/8 = (10÷2)/(8÷2) = 5/4 = 1¼ = 1.25 .
________________________________________________________
Method 3)
________________________________________________________
5/8 * 2 = 5/8 * 2/1 ; The "8" cancels to a "4" ; and the "2" ; cancels to a "1" ;
since: "8÷2=4" ; and since "2÷2=1" ;
________________________________________________
So; we rewrite as: 5/4 * 1/1 = 5/4 * 1 = 5/4 = 1¼ = 1.25 .
_______________________________________________
Method 4)
_______________________________________________
5/8 * 2 = (5÷8) * 2 = 0.625 * 2 = 1.25
