Why can you multiply or divide both terms of a ratio by the same number without changing the value of the ratio?

3:4 = 6:8

\frac{3}{4} =  \frac{6}{8}


The same principle is used with fractions. The identity property of multiplication states that any number times 1 is the same number. Since \frac{2}{2} = 1, the fraction/ratio does not change in value.

Convert 7.7km into miles if 1.6 km = 1 mile
Lemur [1.5K]
This is a simple equation.  

The equation is y = 1.6x  with y being the miles and x being the kilometers.

Lets plug the kilometers in.

Y=1.6(7.7)

1.6 *  7.7 = 12.32

12.32 miles is  equal to 7.7 kilometers

HOWEVER

There are about .6 miles in a kilometer, so if you typed this wrong I don't know.  

It is still the same concept.

Y = .6x

Y = .6(7.7)

.6 * 7.7 =  4.8

In this case there are 4.8 miles in 7.7 kilometers

The amount of tax on a chair was $3.60. The tax rate was 5%. Find the original price of the chair.
marshall27 [118]

9514 1404 393

Answer:

  $72.00

Step-by-step explanation:

The relationship between price and tax is ...

  tax amount = (tax rate) × (price)

Then the price can be found by dividing by the tax rate:

  price = (tax amount)/(tax rate)

  price = $3.60 / 0.05 = $72.00

The original price of the chair was $72.00.

__

Bianca apparently did not pay any attention to the way tax is computed. Nor did she check her work. The original price is not a small fraction of the tax. It is the other way around. Bianca used a wrong relationship between tax and price.
