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
