Question

5/3 + 44/6 - 7

8/15 - 2/5 + 1

3/5 - 7/12 + 4/15

1 - 4/27 + 5/18

25/8 - 27/24 - 37/37

18/18 - 15/30 + 9/6

Answer 1

1)[(2*5)+44-(7*6)]/6=(10+44-42)/6=(54-42)/6=12/6=2
2)[8-(3*2)+15]/15=(8-6+15)/15=17/15
3)[(12*3)-(7*5)+(4*4)]/60=(36-35+16)/60=17/60
4)[486-(4*18)+(5*27)]/486=(486-72+135)/486=549/486 simplificam cu 3=183/162 simplificam cu3 =61/54
5)[(25*111)-(37*27)-(24*37)]/888=(2775-999-888)/888=888/888=1
6)1-15/30+9/6=[30-15+(5*9)]/30=(15+45)/30=60/30=2
