Answer:

c. 21/32 inches

C. 1.992

b. 0.3125

Step-by-step explanation:

Given

The inside diameter = 1/2 inches

Wall thickness = 1/16 inches

clearance = 1/32 inches

As it is given that the outside diameter is twice the thickness and diameter.

So,

Outside diameter = 1/2 + 2(1/32)

= 1/2+2/16

= 1/2+1/8

=(4+1)/8

=5/8

We also have to give clearance of 1/32 inches so,

Diameter of hole = 5/8+1/32

=(20+1)/32

=21/32 inches

So the correct answer for question 1 is:

c. 21/32 inches

<u>Rounding off 1.99235 to three decimal places:</u>

1.992

C. 1.992

<u>Expressing 5/16 as a decimal fraction:</u>

0.3125

b. 0.3125

16 completely divides 5 so the answer is already 4 decimal places ..
