3 2/3 = 3x3=9+2=11/3
4 2/5= 4x5=20+2=22/5
you need to add for number one you need to subtract for number two you need to add for number 3 you need to subtract for number 4
Answer:
It should be reported as 20.648%
Step-by-step explanation:
Since we have 2 different observed values hence we shall use an average of the 2 values to report the result
Thus value is
As we can see that the least count of our observations is upto 3 decimal places hence we have to report a result upto only 3 decimal places thus we need to round off the fourth decimal place thus the digit shall be increased by 1 since we have to drop off 5 and the digit before 5 is 7 which is an odd number.
Thus the result shall be 20.648%
4+3(7+4 x 2)-100
4+3(7+8)-100
4+3(15)-100
4+45-100=
-51
