Step-by-step explanation:

First we need to find the total area of the garden so we can see how many bags she will need. The area of a rectangle is its length multiplied by its width, so the area of her garden is 12 (the length) x 10 (the width). 12 x 10 = 120 square feet. If each bag covers 30 square feet, then she will need 120/30 = 4.

4 bags of fertilizer to cover the 120 square feet of the garden area.

Hope this helped!

The number 412.638 has six digits, three digits before decimal and three digits after the decimal.

Further explanation:

In number every digit has a place value. Place value represent by a digit in a number on the basis of its place in the number defined by place value chart.

From place value chart of decimal numbers, expand the number 412.638 in fraction as follows:

$\begin{aligned}412.638&=4\times\left({\dfrac{{100}}{1}}\right)+1\times\left({\dfrac{{10}}{1}}\right)+2\times\left({\dfrac{1}{1}}\right)+6\times\left({\dfrac{1}{{10}}}\right)+3\times\left({\dfrac{1}{{100}}}\right)+8\times\left({\dfrac{1}{{1000}}}\right)\\&=\dfrac{{400}}{1}+\dfrac{{10}}{1}+\dfrac{2}{1}+\dfrac{3}{5}+\dfrac{3}{{100}}+\dfrac{1}{{125}}\\\end{aligned}$

Therefore, the expanded form for 412.638 in fractions is $\boxed{\dfrac{{400}}{1}+\dfrac{{10}}{1}+\dfrac{2}{1}+\dfrac{3}{5}+\dfrac{3}{{100}}+\dfrac{1}{{125}}}$ .

So, Nancy write the number in the form $\boxed{\dfrac{{400}}{1}+\dfrac{{10}}{1}+\dfrac{2}{1}+\dfrac{3}{5}+\dfrac{3}{{100}}+\dfrac{1}{{125}}}$ .

From place value chart of decimal numbers, expand the number 412.638 as follows:

$\begin{aligned}412.638&=4\times\left({100}\right)+1\times\left({10}\right)+2\times\left(1\right)+6\times\left({0.1}\right)+3\times\left({0.01}\right)+8\times\left({0.001}\right)\\&=400+10+2+0.6+0.03+0.008\\&=400.000+10.000+2.000+0.6.000+0.03.000+0.008.000\\\end{aligned}$

Therefore, the expanded form for 412.638 in decimals is $\boxed{400.000+10.000+2.000+0.600+0.030+0.008}$ .

So, Charles write the number in the form $\boxed{400.000+10.000+2.000+0.600+0.030+0.008}$ .

Thus, the expanded form for 412.638 in fractions is $\boxed{\dfrac{{400}}{1}+\dfrac{{10}}{1}+\dfrac{2}{1}+\dfrac{1}{6}+\dfrac{1}{{30}}+\dfrac{1}{{800}}}$ and in decimals is $\boxed{400.000+10.000+2.000+0.600+0.030+0.008}$ .
