Answer:
Relative Size, S, is 1584.89
Step-by-step explanation:
The equation is 
Where,
- R is the measurement in Richter Scale
- S is the relative size of the earthquare
<u>It is given that in Richter Scale, an earthquake measured 3.2, so
.</u>
<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

<em>Converting to exponential form, we have:</em>

<em>Rounding to nearest hundredth, we have:</em>

Your answer was correct . Maybe you have an extra space in your answer ? I worked out the problem twice and got -49/8, -163/8
Answer:
When a number is written using a whole number plus a portion of one, with the portion separated from the whole number by a dot, is called a <u><em>mixed fraction</em></u>.
Step-by-step explanation:
A fraction is a number that is obtained by dividing an integer into equal parts and is expressed as:

An improper fraction is a fraction in which the numerator, that is, the top number, is greater than or equal to the denominator, that is, the bottom number. In contrast, in proper fractions, the numerator is less than the denominator.
Improper fractions can be represented as mixed fractions. A mixed fraction represents a whole number and a proper fraction, in other words, it corresponds to the sum of a whole part plus a fractional part. In summary, mixed fractions are made up of an integer part and a fractional part.
So, <u><em>when a number is written using a whole number plus a portion of one, with the portion separated from the whole number by a dot, is called a mixed fraction.</em></u>
