Question

Вычислите:4 1/6*(1 1/2-3/5)+(3/4+5/6)*6

Answer 1

1) 11/2 - 3/5 = (5*11 - 2*3) / 10=49/10
2) 3/4 + 5/6 = (3*3 + 5*2) / 12= 19/12
3) 4 1/6 * 49/10 = 25/6 *49/10= (25*49)/ (6*10)= 245/12
4) 19/12 * 6 = (19*6) /12 = 19/2
5)245/12+ 19/2 = (245+ 19*6) / 12= (245+114)/2= 359/2= 179 1/2 

Answer 2

4 1/6 x ( 1 1/2 - 3/5) + (3/4 + 5/6) x 6 = 12. 1) 1 1/2 - 3/5 = 3/2 - 3/5 = 15/10 - 9/10 = 6/10. 2) 4 1/6 x 6/10 = 25/6 x 6/10 = 2 1/2. 3) 3/4 + 5/6 = 9/12 + 10/12 = 19/12. 4) 19/12 x 6 = 19/2 = 9 1/2. 5) 2 1/2 + 9 1/2 = 12.
