"Percent" means "per 100" or "over 100". So, to convert 0.068 to percent we rewrite 0.068 in terms of "per 100" or over 100.
Multiply 0.068 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.
[tex]\frac{0.068}{1}[/tex] × [tex]\frac{100}{100}[/tex] = [tex]\frac{6.8}{100}[/tex]
6.8/100 is 6.8 over 100 and means 6.8 per 100. 6.8 "per 100" means 6.8 "percent" or 6.8%
Therefore, we have shown that
0.068 = 6.8%
