Sixth grade on the calculation problem, fraction mixed operation, can calculate the simple calculation One seventh by six thirteen plus eight thirteen by one seventh Half divided by four fifths plus one and two ninths 3 / 7 divided by [(3 / 2 minus 1 / 2) times 6 / 7] (2 / 3 minus 1 / 2) divided by (5 / 3 times 5 / 6) (2 / 3 minus 1 / 2 divided by 5 / 3) times 5 / 6 Eight fifteen times three twentieth divided by fifteen seventeen 11 / 17 divided by 33 / 34 multiplied by 2 / 5 Seven out of twelve times (four out of seven plus four out of fourteen) Three eighths by two fifths plus two fifths divided by eight fifths Five sixths by seven tenths divided by fourteen thirds
I hope these problems are what you need and can give you some help. 1 / 7 by 6 / 13 plus 8 / 13 by 1 / 7 × 6 / 13 + 8 / 13 × 1 / 7 = 1 / 7 × (6 / 13 + 7 / 13) = 1 / 7 × 1 = 1 / 7 half divided by 4 / 5 plus 1 and 2 / 9 1 / 2 △ 4 / 5 + 11
