Answer: -12.5
Step by step explanation
Answer:
12/49
Step-by-step explanation:
First write 2 1/3 as a improper fraction, to do that, first multiply the 2 by the denominator, then add it with the 1, which will result in 7/3
when doing division of fraction you have to remember this, KFG
KFG: Keep Flip Change
you keep the first number or fraction, which is 4/7
then you flip the sign, so you change division in to multiplication
after that, you change or write the reciprocal of the second number or fraction, so 7/3 will be 3/7
Now the equation is
4/7 times 3/7, which is 12/49
Answer:
81.25%
Step-by-step explanation:
Given that :
Engine power = 240 hp
Power delivered to drive wheel = 195 hp
Efficiency = (power delivered to drive wheel / Engine power) * 100%
Efficiency = (195 / 240) * 100%
Efficiency = 0.8125 * 100%
Efficiency = 81.25%
The efficiency of transmission and drive mechanism is 81.25%
