Use equivalent ratios to find the unknown value.
2
The unknown value is

Unknown number = 36

Step-by-step explanation:

Equivalent ratio means,

If and ,

By cross multiplication,

2 × y₂ = 8 × 9

2y₂ = 72

y₂ = 36

Therefore, missing number in the denominator of the fraction will be 36.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
