Question

28 1/2 divided by 1/2

Answer 1

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

Answer 2

$\frac{28.5(2)}{0.5(2)} = \frac{57}{1} = 57$

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!
