How to reduce a ratio to lowest terms
aleksley [76]

It is usual to represent ratios in their simplest form so that we are not operating with large numbers. Reducing ratios to their simplest form is directly linked to equivalent fractions.

For example: On a farm there are 4 Bulls and 200 Cows. Write this as a ratio in its simplest form.

Bulls <span>: </span>Cows

4 <span>: </span>200

If we halve the number of bulls then we must halve the number of cows so that the relationship between the bulls and cows stays constant. This gives us:

Bulls <span>: </span>Cows

2 <span>: </span>100

Halving again gives us

1 <span>: </span>50

So the ratio of Bulls to Cows equals 1 : 50. The ratio is now represented in its simplest form.

An example where we have 3 quantities.

On the farm there are 24 ducks, 36 geese and 48 hens.

Ratio of ducks <span>: </span>geese <span>: </span>hens

24 <span>: </span>36 <span>: </span>48

Dividing each quantity by 12 gives us

2 <span>: </span>3 : 4

So the ratio of ducks to geese to hens equals 2 : 3 : 4 which is the simplest form since we can find no further common factor.

R=P over I squared. Solve for I.
kirza4 [7]

Answer: I=sqrt(P/R)

Step-by-step explanation:

R=p/I^2

Multiple l squared on both sides...

(I^2) R=p/l^2 (l^2)

R(I^2)=p

Separate I by dividing both sides by R...

I^2=p/R

Square root both sides...

I=sqrt(P/R)

How long would it take franklin to shovel the driveway alone?
motikmotik

Answer:

Time taken by Franklin to shovel alone is 65.5 minutes.

Step-by-step explanation:

Let the time taken by Franklin to shovel alone = x minutes.

Since, the time taken by Angela to shovel = 180 minutes and the time taken by both = 48 minutes.

Then, we have,

Amount of shoveling done in 1 minute by Angela = \frac{1}{180}

Amount of shoveling done in 1 minute by both = \frac{1}{48}

Amount of shoveling done in 1 minute by Franklin= \frac{1}{x}

So, we have,

\frac{1}{180}+\frac{1}{x}=\frac{1}{48}

i.e. \frac{x+180}{180x}=\frac{1}{48}

i.e. 48(x+180)=180x

i.e. 48x+8640=180x

i.e. 132x=8640

i.e. x= 65.5 minutes

Thus, the time taken by Franklin to shovel alone is 65.5 minutes.
