Which statement best explains whether using a calculator or determining the solution by hand would be the most efficient way to fully simplify the expression Seven-ninths plus seven-ninths plus five-fifths minus 3? The fractions have different denominators, making the calculations time consuming to do by hand, so using a calculator will be more efficient. Adding and subtracting fractions with only two different denominators is always a quick calculation to perform by hand, so this expression can be easily simplified without the use of a calculator. The first calculation cannot be done quickly by hand, so using a calculator will be more efficient. The first two terms cancel each other out and the third term is equal to 1, so this expression can be easily simplified without the use of a calculator.
