What's 2/5 divided by 4 ( simplest form)

1/10

Step-by-step explanation:

To divide fractions, you can use the "keep, change, flip" method.

1. Keep the first fraction as-is (2/5)

2. Change the division sign to a multiplication sign

3. Flip the second fraction (i.e. find the reciprocal). In this case, 4/1 becomes 1/4.

Plug in the Values:

2/5 x 1/4

Multiply the numerators and the denominators together, respectively.

2/20

Simplify by dividing by the GCF.

1/10

1/10

Step-by-step explanation:

we multiply by the reciprocal when we work with fractions and division.

Now you just multiply across.

Therefore, you have 2/20, which simplifies to 1/10.

The volume of the sphere in cubic inches is option D) 1767.1

Step-by-step explanation:

Given,

The diameter of the sphere = 15 inches

The radius of the sphere, r = diameter/2

                                             =15/2

                                           r =7.5 inches

The volume of the sphere = 4/3 πr^3

⇒ 4/3 π(7.5)^3

⇒ 4/33.14421.86

⇒ 1766.25 cubic inches

⇒ 1767 cubic inches (approximately)
