Phil served 2/8 of an apple pie because in order to have a common denominator, you need to multiply 1/4 by 2/2.
Phil served 2 more pieces of blueberry than apple pie because 1/2(4/4) = 4/8, and 4/8 - 2/8 = 2/8.
Answer:
6.3 Kwhr
Step-by-step explanation:
Given :
Power = 8827 watts
Time in minutes = 43 minutes
To obtain the amount of CO2 that was created :, which is the energy :
Recall
Energy = power * time
Energy in kw/hr = (8827/100) * (43/60)
Energy = 8.827 * 0.7166666
Energy = 6.326 Kwhr
The answer is 8 and 3 fourths which would be written as 8 3/4
