Hello everyone, I am going to try to make you understand this question.
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.
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.
