Answer:
After correcting error of Mia and solving the expression we get 14.25
Step-by-step explanation:
The given expression is:
First I solve the expression, and then will point the error
So, the mistake Mia did was when she inverted division sign into multiplication, she didn't invert the term next to division sign.
The step she did was:
While the correct step was:
After correcting error of Mia and solving the expression we get 14.25
Since you can directly sum two fractions with the same denominator, we can rearrange the sum as follows:
Now we can sum the first two fraction easily:
We can simplify the first fraction: 12/16=3/4. So, we can sum the two fractions again because they have the same denominator:

Answer:
64 times more paint will be needed since the volume of the second is 64 times the volume of the first
Step-by-step explanation:
If the original sphere is 12 cm diameter
its radius will be half this measure which is 12/2 = 6 cm
The new diameter is 4 times this, so its radius would be 4 times this and it is 24 cm
Now, the volume of the sphere means we have to raise the power of the radius by 3
The other terms in the formula remains the same for both, so we are simply comparing the radii
so we will have the difference in volume in times of multiples as ;
(24/6)^3 = 4 * 4 * 4 = 64
