b) 3,7 - 1,2 : 1/2 = 3,7 - 1,2 *2 = 3,7 - 2,4 = 1,3
c) 5 * 0,3 + 3 * 2/5 = 1,5 + 6/5 = 1,5 + 1,2 = 2,7
d) 1,2 : 1/3 - 1,4 * 2/7 = 1,2*3- 7/5*2/7= 3,6- 2/5 = 3,6 - 0,4 = 3,2
2.Oblicz:
a) 1/2 * (4/5 + 1,2) = 1/2 *(0,8+1,2)= 1/2 * 2=1
b) (3/4 - 1/5) : 0,5 = (0,75-0,2)*2 = 0,55 * 2=1,1
c) (1 1/5 - 0,5 ) *3 1/3= (1,2-0,5)* 10/3= 0,7 * 10/3 = 7/10*10/3= 7/3= 2 1/3
d) (5,6 - 3,1) :3 1/2 = 2,5: 7/2= 2 1/2*2/7 = 5/2 * 2/7 =5/7
