Gina is weighing her lawn ornaments. Her flamingo weighs 4.168 pounds, and her garden gnome weighs 1.963 kilograms. There are 2.20462 pounds in a kilogram. Which ornament is heavier, and by what percent?

a.

The flamingo is 112.33% heavier than the gnome.

b.

The flamingo is 89.06% heavier than the gnome.

c.

The gnome is 45.36% heavier than the flamingo.

d.

The gnome is 3.84% heavier than the flamingo.

The answer is d.

The gnome is 3.84% heavier than the flamingo.

Flamingo weight:

w1 = 4.168 pounds

Garden gnome weight:

w2 = 1.963 kilograms.

There are 2.20462 pounds in a kilogram:

1 kilogram = 2.20462 pounds

1.963 kilograms = ? pounds

Make a proportion:

1 kilogram : 2.20462 pounds = 1.963 kilograms : x

x = 2.20462 pounds * 1.963 kilograms : 1 kilogram

x = 4.328 pounds

It is obvious that 4.328 pounds is bigger than 4.168 pounds, thus Garden gnome is heavier than flamingo. Now, calculate by what percent:

4.328 pounds are 100% and 4.168 pounds are x.

4.328 pounds : 100% = 4.168 pounds : x

x = 100% * 4.168 pounds : 4.328 pounds

x ≈ 96.16%

The difference between two weights is: 100% - 96.16% which is how much the gnome is heavier than the flamingo.
