4 and 1/3, u can turn them into improper fractions and subtract the numerators
It would take 93.33 hours to use 14 kilowatt hours of electricity.
Step-by-step explanation:
Given,
Electricity used in one hour = 3/20 kilowatt hours
Ratio of time to electricity = 1 : 3/20
Let,
x be the number of hours to use 14 kilowatt hours electricity.
Ratio of time to electricity = x : 14
Using proportion;
Ratio of time to electricity :: Ratio of time to electricity
Product of mean = Product of extreme
Multiplying both sides by 20/3
It would take 93.33 hours to use 14 kilowatt hours of electricity.
