Shirley has 18 coins. One sixth of the coins are quarters, one third of the coins are dimes, and one half of the coins are nickels. What is the value of Shirley's coins?

1/6 of 18 =3
so shirley has 3 quarters =75 cents
1/3 of 18=6
so shirley has 6 dimes =60 cents
and 1/2 of 18=9
so shirley has 9 nickels= 45 cents
75+60+45=180 cents
