there are 100 pennies in a dollar what fraction of a dollar 61 pennies right as a fraction as a decimal
Assoli18 [71]
So fraction is (parts)/(total)

percent means parts out of 100 so x percent=x%=x/100 so
61 out of 100=61/100=61%

if you simplify 61/100,
61/100=6.1/10 times 10/10=6.1/10 times 1=0.61/1 times 10/10=0.61/1 times 1=0.61


fraction=61/100
decimal=0.61
