Tomas bought a bottle of shampoo that held 10.5 fluid ounces. He uses 1/16 of the shampoo every time he washes his hair. How many ounces of the shampoo are left after he washes his hair 6 times?

10 1/2 * 16 = 21/2 * 1/16 = 21/32

 

21/32 * 6/1 = 12/32

 

126 / 32 = 3

 

 

8/16 + 16/16 = 24/16

 

10 1/2 - 3 15/16 = 6 9/16

1/16*6 = 6/16 = 3/8

5/8 left. 

5/8*10.5 = 6.5625
