 an equation<span> is a statement of an equality containing one or more variables</span>
Brut [27]3 years ago

An equation is a mathematical sentence that contains an equal sign.

To understand this further, I'll show an example.

<em>Suppose that we had a balance and a bunch of blocks for reference. If we put the bag on one side of the balance and put a number of blocks on the other side of the balance, they even out. If the number of blocks on the right side of the balance is 8, this means that the number of blocks in the bag is 8. We can write this as X = 8.</em>

<em />

<em>X = 8 is an example of an equation since it's a mathematical sentence that has an equal sign in it.</em>

In converting 10 inches to centimeters, what unit (omit the number) would you place in the numerator of your ratio?
belka [17]

Answer:

  centimeters

Step-by-step explanation:

The numerator of the conversion factor always has the "to" units. The denominator has the "from" units. That way, when you multiply, the "from" units cancel:

  (xx <em>from</em>) · (yy <em>to</em>)/(zz <em>from</em>) = xx·yy/zz · (<em>from/from</em>) · <em>to</em> = xx·yy/zz · <em>to</em>

Here, you want to convert to centimeters, so centimeters will be the units in the numerator.

  10 in · (2.54 cm)/(1 in) = 25.4 cm

_____

The conversion factor is always "1". That is, the numerator and denominator are always <u>equal</u> in value. Here, 2.54 cm = 1 in, so (2.54 cm)/(1 in) = 1. You can multiply by 1 anytime you like. For units conversion, it only has the effect of changing the units.
