If you can expplain
lana [24]

Answer:

I can explain.  The answer is A

Step-by-step explanation:

Think of it this way: when you write a mixed number, the fraction is out of 100.    If the denominator is 8, find 1/8 of 100 by doing 100 divided by 1/8.  This gives you 12.5.  The entire fraction is 2/8, so we need to multiply 12.5 by 2, since it's only 1/8.  12.5 x 2 gives us 25.  In the decimal, this would be equal to .25.  A is the only answer that represents the mixed number as a decimal correctly.

14 is 28% of what number
Sindrei [870]
'is' in mathematics means the equal sign
'of' in mathematics means the multiplication sign
the number can be any variable you chose it to be

14 = \frac{28}{100} \times x

Divide both sides by 28

\frac{1}{2} = \frac{x}{100}

Multiply by 100 on both sides to isolate 'x'

\boxed{\bf{x=50}}

14 is 28% of 200

andre [41]
For this question, we can divide both numbers by 8, as they are both divisible by 8. Then, we will be left with our answer, which will be a 3 degree drop every hour.
