By dividing by 12:
100 in/min (1/12 ft/in) = 100/12 ft/min = 25/3 ft/min

Answer:

The conversion will give the answer : 8 1/3 feet/minute or 8.33 feet/minute

Step-by-step explanation:

We know that 1 feet = 12 inches.

Or, 12 inches = 1 feet

So, 100 inches will be : $\frac{1}{12}\times100$ feet

Now, using both the units - feet per minute, we can write as :

100 inches/1 minute x 1 foot/12 inches

=> (100/12) feet/minute = 8 1/3 feet/minute or 8.33 feet/minute

Is 8/5 proportional to 24/15 ?

DiKsa [7]

Hey there!

The answer to your question is, yes, it is

Given:

$\frac{8}{5}$ $and$ $\frac{24}{15}$

To see if they are equal, we can use cross products (see below for information about this, if you don't know what it is). Let us assume they are equal. This would mean that:

$8*15=24*5$

Let's solve it and see if it is true:

$8*15=24*5$

$120=120$

Therefore, they are proportional.
