Answer:
4 : 5
Explanation:
80 percent can be written as:
80/100
Now we can reduce the above fraction to its lowest term as shown below
80/100 = 8/10
Divide both the numerator and denominator by 2.
8/10 = 4/5
Now, we can not divide further. So the ratio becomes 4 : 5
The equivalent temperature in degree Celsius would be 93
