Excel/calc percent help please

[chili]

Using libre office version of excel/calc and cannot figure out what is probably a simple formula

i have 3 cells a1 b1 c1 if

a1 holds the gross value of an item (375000.00)
b1 holds the value of several times a1 (2250000.00) 6 x a1

how could i get cell c1 to display a percentage of the value of b1 in this case 80% / 1800000.00


thanks

=b1*0.8

=b1*(80/100)
