Step-by-step explanation:
The answer is 33/5.
To multiply fractions, you multiply the numerators to get the numerator of the product and multiply the denominators to get the denominator of the product and then simplify the product. Also, you can make a whole number, which is 28 in this case, into a fraction by putting it over 1. So, that would be 28/1.
First, I multiplied the numerators:
4(11)(28)(9) = 11088
Next, multiply the denominators (and im assuming that last one is a 48, its a bit covered up by the mouse):
5(7)(1)(48) = 1680
So that's 11088/1680
Lastly, you simplify this to get 33/5 (I just used desmos scientific calculator for all of this)
Hope that helps :]
