Ollie drank 3/4 of a fl oz bottle of juice. How many fl oz of juice are left in the bottle

1/4 because 4/4-3/4=1/4

Answer=12 oz

3/4*16=12 ounces

you could also solve this by going on a calculator and converting 3/4 to a decimal

3/4=0.75

0.75*16=12 ounces

or you could make 16 squares, and shade in 3 out of every 4. so like 'shade, shade, shade, skip' and repeat that until you get to the end, then you'd end up with 12 shaded
