Hey there!

When we multiply fractions and whole numbers, we simply take that whole number and put it over them, and just multiply across. That gives us:

\frac{1}{2}x*8 = \frac{8}{2} = 4

Notice how it's four, because when we have a fraction, we divide. 8 divided by 2 equals four. Next:

\frac{1}{4} *4 = \frac{4}{4} = 1

4/4 is equal to 1 because 4 divided by 4 is one. 4 goes into 4 once. Next, we have:

\frac{1}{3}*6 = \frac{6}{3} = 2

That's because 6/3 = 2.

Hope this helps!

The length of each edge of a cube is decreased by 40 percent By what percent does the volume of the cube decrease? Express your
lora16 [44]

Answer:

78% (to the nearest tenth)

Step-by-step explanation:

Volume of a cube = (length )³

Let the length of the cube = y

Original volume = y³

if the length is decreased by 40%, then new length = 1- (40% of y)

                                                                                     = 1-0.4y

                                                                                     =  0.6%

New volume (after decreasing the length) = (0.6y)³

                                                                      =  0.216‬‬y³

% Volume decrease = (Original volume - New volume)/Original Volume x 100%

                                 =  (y³ - 0.216‬‬y³)/ y³  x 100%

                                 = 0.784y³/y³  x 100%

                                 =78.4%

                                ≈78%
