Exactly the same way you would do it if it were a proper fraction . . .
multiply the numerator by the whole number, and then clean up
the fraction.

Turn the whole number into a fraction and then multiply straight across
EX:                    3 times 15/10
Change 3 into 3 over 1   3/1
All you have to do next is multiply 3 by 15 and 1 by 10
3 times 15 is 45 and 1 times 10 is 10 
The improper fraction after multiplying is 45/10
If you wanted to simplify that it would be 4 1/2

Answer:

The volume of can A is half the volume of can B.

Step-by-step explanation:

Given

Can A and Can B

Required

The true statement

For Can A, we have:

h =8

r = 0.5

The volume is:

Volume = \pi r^2h

This gives:

V_A = \pi * 0.5^2 * 8

V_A = \pi * 2

V_A = 2\pi

For Can B, we have:

h =4

r = 1

The volume is:

Volume = \pi r^2h

This gives:

V_B = \pi * 1^2 * 4

V_B = \pi  * 4

V_B = 4\pi

So, we have:

V_A = 2\pi

V_B = 4\pi

By comparison, (d) is correct
