The closest option to the actual answer is a.
1 5/18 is the actual answer.
If you make both the denominators the same, then you can actually add the fractions together.
To make both of the denominators the same, you need to multiply 5/6 by 9 and 4/9 by 6, which would result in 45/54 + 24/54= 69/54 = 23/18. If we convert it to a mixed fraction, it would result into 1 5/18.
Well, you would have to move the decimal on both of them (however many times the exponent number is) for both to get them to normal numbers then do the math with normal numbers and switch back to a scientific notation with the final answer
THE CORRECT ANSWER CAN BE 1 750/1000 OR 1 I/2
5−8
