Answer: 57
Step-by-step explanation:
28 1/2 / 1/2
make 28 and 1/2 into 57/2
so now 57/2 divided by 1/2
the same as 57/2 times 2/1
multiply straight across
(57)(2)/(2)(1)
114/2
57
[tex] \frac{28.5(2)}{0.5(2)} = \frac{57}{1} = 57[/tex]
Multiplying both the nominator and denominator by 2 will give you a denominator of 1. Dividing any value by half is always equals to twice the value.
Hope this helps!
