Given:
.
%284.5+%2A+10%5E12%29%2F%281.5+%2A+10%5E7%29
.
The numerator has two factors ... 4.5 and 10%5E12
.
The denominator also has two factors ... 1.5 and 10%5E7
.
The way to do this problem is to divide the factor 1.5 in the denominator into the
factor 4.5 in the numerator. The result of this division is 3.0.
.
Then divide the factor 10%5E7 in the denominator into the factor 10%5E12 in the
numerator. Since these two factors both have the base 10 the division just involves
subtracting the exponent of the denominator from the exponent of the numerator. The result is:
.
10%5E12%2F10%5E7+=+10%5E%2812-7%29+=+10%5E5.
.
Combining these two results leads to the answer of 3.0+%2A+10%5E5 and this is in scientific
notation.
.
Hope this helps you to see how to work the problem.
