Fractions can be more precise than decimals. For example: 1/3 can not be expressed exactly as a decimal. .33333333333333333333333333333333333333333... is only an approximation.
Some numbers cannot be expressed precisely as either a fraction or a decimal. pi is an example.

I agree with Bilral,

Fractions can be more precise than decimals.

For example, 1/3 is 1.3333......, but we often write it as 1.33. Clearly 1/3 is more precise than 1.33.

Good luck,

Paul

To tringles are similar and they want to find the ratio from the height to the base? the first tringle has the height of 6 and the base 8 and the second tringle has the height of 3 and the base 4


That ratio is 3/4, height/base, in both triangles. Is that what you mean?

Ratios are normally expressed as a fraction, not a decimal.

2 feet 8 inches is is 32 inches.

4,500 x 32 is 144,000 inches

divide it by 12 to to bring it back to feet. The answer is 12,000.

When working in feet, which have 12 inches, it is easier to bring to a single figure rather than using fractions. This is the benefit of the Metric system as everything is based on 10s and hundreds and thousands. Millimeters, Centimeters and Metres.
