Answer:

0.375 pounds of melon was given away by Melanie.

Step-by-step explanation:

We are given the following in the question:

Initial weight of melon =

$1\dfrac{1}{8}\text{ pounds}$

Wait of remaining piece =

$\dfrac{6}{8}\text{ pounds}$

Pounds of melon Melanie gave away =

Initial weight of melon - Wait of remaining piece

$= 1\dfrac{1}{8} - \dfrac{6}{8}\\\\=\dfrac{9}{8}-\dfrac{6}{8}\\\\=\dfrac{3}{8} = 0.375\text{ pounds}$

Thus, 0.375 pounds of melon was given away by Melanie.

Answer:

26.8cm²

Step-by-step explanation:

the area if a rectangle is 53.6cm^2.If the length is multiplied by four and the width is halved, the area would then be?

Area of rectangle = length x width

53.6 = 4L x 1/2 W

53.6 = 2L × W

Divide both sides by 2

L × W = 53.6 ÷ 2

New area = 26.8cm²
