Question

calculcati : [ 5 intreg 2/3 + 1 , ( 5 ) -2 ] : 15 intreg 2/7 b ) [ 4+6 intreg 2/3 - 2 intreg 1/4 * ( 2/3-2/9 ) ] : 4 intreg 5/6 + 29/4

Answer 1

a) $(\frac{10}{3} + 5 - 2) \times \frac{1}{15} \times \frac{2}{7} \\ = ( \frac{10}{ 3} + 3 )\times \frac{1}{15} \times \frac{2}{7} \\ = \frac{19}{3} \times \frac{1}{15} \times \frac{2}{7} \\ = \frac{38}{315}$

b) (8-2/9) × 1/4×5/6+29/4
70/9×1/4×5/6+29/4
175/108+29/4
479/54
