To find a ratio equivalent to 978, we need to calculate the decimal values of the fractions given in the responses and compare them with 978.
Let's convert the fractions to their decimal equivalents:
-
For \( \frac{3}{18} \): \[ \frac{3}{18} = 0.1667 \]
-
For \( \frac{1}{3} \): \[ \frac{1}{3} = 0.3333 \]
-
For \( \frac{1}{8} \): \[ \frac{1}{8} = 0.125 \]
Now, let's look at the whole numbers:
- 318
- 13
- 18
- 326
None of the decimal values or whole numbers are equal to 978.
To determine which number or fraction might be associated with the concept of being "equivalent" in another context, we need more information. Typically, a ratio equivalent to a number indicates that it can be expressed in another form relating to that number through multiplication or division by a common factor.
If we simply want the option that is numerically closest to 978, it's clearer if we compare the options directly:
- 318 is significantly less than 978.
- 13 is also much less than 978.
- 18 is also far less than 978.
- 326 is still much less than 978.
In conclusion, none of the provided ratios or numbers are equivalent to 978 in a direct mathematical sense. It seems there has been a misunderstanding, as none of the options are equivalent to 978. If the question was misinterpreted, could you clarify or provide additional context?
