First, you turn the fractions into decimals.
7/16=0.4375
_
4/3=1.3
1/2=0.5
Then, you would multiply them all together.
Once you multiply, you should then get 7/24 in it's decimal form. The way that I figured that out is by Dividing all of the answer choices and C.7/24 equals the same as all of the fractions together.
Hope this helps! :)
