Use unit multipliers to convert 123 pounds per mile to ounces per centimeter. There are 5,280 feet in 1 mile. There are 16 ounce
gregori [183]
A unit multiplier is a conversion factor of value 1 that we can use to convert quantities.
We want to convert 123 pounds per mile to ounces per centimeter. 
First, we are going to express the quantity to convert as a fraction:
123 pounds per mile=123 \frac{pounds}{mile}

Next, we are going to find our multipliers:
- We know for our problem that there are 5,280 feet in 1 mile, so our first multiplier will be: \frac{1mile}{5280ft}
- We also know that there are 16 ounces in 1 pound, so our second multiplier will be: \frac{16ounces}{1pound}
- We know that there are 12 inches in 1 foot, so our third multiplier will be: \frac{1ft}{12in}
- We know that t<span>here are approximately 2.54 cm in 1 inch, so our fourth multiplier will be: </span>\frac{1in}{2.54cm}

Now we can put all our multipliers together:
123 \frac{pounds}{mile} * \frac{1mile}{5280ft}*\frac{16ounces}{1pound}* \frac{1ft}{12in}*\frac{1in}{2.54cm}=0.01 \frac{ounces}{cm}

We can conclude that the answer is 0.01

Simplify: 
(7/9)/(3/5)
Multiply the numerator by the reciprocal of the denominator, (7/9)/(3/5) = 7/9×5/3:
(7×5)/(9×3)
9×3 = 27:
(7×5)/27
7×5 = 35:
