My Blog question is:
To calculate -3/4 + (-2/ 3), Amy decided to convert the fractions to decimals and convert the decimals on a scientific calculator.
a) Explain why she had difficulty in determining the exact answer by this method.
b) How should she calculate to get an exact answer?
A) Amy had a problem with this question because -2/3 is a repeating number. She would have to round the decimal which would not give her an exact answer.
B)
The decimal equivalent to -1 5/12 is -1.41666... repeating.
The fraction is in its lowest terms so it can't be simplified anymore. And I guess we are done.

Hey Vikram! This is a nice post! However, it just just a few minor errors. Beside your picture you wrote "The Decimal equivalent to ..." Instead you should have put "The decimal equivalent to..." The D is capitalized when it shouldn't be. There are some slight grammatical errors as well. Be sure to check over your post before posting. Great job!
Thanks Vikram. A quick minor fix to we're done from were done. Otherwise nicely done.
Good Job Vikram ! Again no mistakes other than the ones Mr. Backe and Linda pointed out, I tried to look for more but there's none. good Job and very well explained.
