Answer:

\frac{7}{4}  -  \frac{3}{4} =  \frac{4}{4}

Step-by-step explanation:

To find the number midway between 3/2 and 4/2, add them up and divide by 2

we have, 3/2 + 4/2 = 7/2

7/2 ÷ 2 = 7/4

Repeat the same for the number midway between 1/2 and 2/2 to get 3/4

The answer then is, 7/4 - 3/4 = 4/4

How fast does a driven gear turn if it has 25 teeth (t) and is driven by a10-tooth driver gear (T) at 250 RPM?
vazorg [7]

Given:

The number of teeth = t = 25

The gear is driven by a 10-tooth driver gear (T) at 250 RPM

Let the speed = s

So, using the ratio and proportion

\frac{25}{s}=\frac{10}{250}

Solve for s:

\begin{gathered} 10s=25\cdot250 \\  \\ s=\frac{25\cdot250}{10}=25\cdot25=625 \end{gathered}

So, the fear will be driven by 625 RP
