All you do is multiply the left column to get the right column
or
to divide the right column to get the left column.

So you want to go from left to right in the first row. 6*4 = 24
Second Row is complete.
Third row is Right to left so you would divide by 4 which will give 12
Fourth row multiply by 4 ; 4 * 15 = 60

Answer:

Corresponding side of AB is FE

Corresponding side of CB is DE

Corresponding side of AC is FD

$k =2$

$DE = 6$

$FD=10$

Step-by-step explanation:

Given

$\triangle ABC$ and $\triangle FED$

See attachment for triangles

Solving (a): Corresponding side of AB

Going by the names of the triangle, the corresponding sides are:

AB and FE; CB and DE; AC and FD

Hence, the corresponding side of AB is FE

Solving (b): Corresponding side of CB

This has been solved in (a) above.

The corresponding side of CB is DE

Solving (c): Corresponding side of AC

This has been solved in (a) above.

The corresponding side of AC is FD

Solving (d): Scale factor from ABC to FED

To do this, we simply divide the lengths of corresponding sides.

The scale factor k is:

$k = \frac{FE}{AB}$

$k = \frac{8}{4}$

$k =2$

Solving (e): Length of DE

We make use of the scale factor calculated in (d) above

$k = \frac{DE}{CB}$

$2 = \frac{DE}{3}$

$DE = 2 * 3\\$

$DE = 6$

Solving (f): Length of FD

Using Pythagoras:

$FD^2 = DE^2 + EF^2$

$FD^2 = 6^2 + 8^2$

$FD^2 = 100$

$FD = \sqrt{100$

$FD=10$

How do I divide 6.4 into 0.08

Vitek1552 [10]

Ok I think you mean what is 6.4 divided by 0.8.

You can either use long division or a calculator. However since 6.4 divided by 0.8 is really the fraction 6.4/0.8 you can turn this into a much more simple problem.

Just $\frac{6.4}{0.8}$ ×
