Don’t know if I got this right or not could u guys help.

Answer 1

Yes you got it correct.

Answer 2

Hi!

Let's check your answer by doing the opposite.

-----------------------------------

The way to find the area of a rectangle is multiplying the width by height. So you need to multiply

$3\frac{1}{8} * 6\frac{2}{5} = ?$.

The opposite of multiplying those, is dividing them.

$? / 3\frac{1}{8} = 6\frac{2}{5}$

Now since you're saying the answer is 20, put in the value.

$20 / 3\frac{1}{8} = 6\frac{2}{5}$

----------------------------------

Convert the mixed numbers to improper fractions by multiplying the whole number by the denominator then adding it to the numerator. The denominator stays the same.

3 * 8 + 1 = 25

6 * 5 + 2 = 32

$20 / \frac{25}{8} = \frac{32}{5}$

--------------------------------

Now solve.

$\frac{160}{25} = \frac{32}{5}$

Simplify

$\frac{32}{5} = \frac{32}{5}$

------------------------------------------

Your answer is correct!

Hope this helps! :)
