(1/2 + 2 1/2 ) : 7 - 1/2 * 2/3 + 1/3 =3/7
1) 1/2 + 2 1/2 = 3
2) 3: 7 = 3/7
3) 1/2 * 2/3 = 1/3
4)3/7 - 1/3 = 9/21 - 7/21 = 2/21
5)2/21 + 1/3 = 2/21 + 7/21= 9/21= 3/7
(3/4 : 3/100 - 23 1/2) : 1 1/2 * 2/3 + 1 1/6 =1 5/6
1) 3/4 : 3/100 = 3/4 * 100/3 = 100/4 = 25
2) 25 - 23 1/2 = 1 1/2
3) 1 1/2 : 1 1/2 = 3/2 * 2/3 = 1
4) 1* 2/3 = 2/3
5) 2/3 + 1 1/6 = 4/6 + 1 1/6 = 1 5/6
(8,75 - 2 5/6 ) : 7,1 + (4 1/2 + 2 2/3) : 4 3/10 =2 1/2
1) 8,75- 2 5/6 = 875/100 - 17/6 = 35/4 - 17/6 =
= (105-34) / 12 = 71/12 = 5 11/12
2) 4 1/2 + 2 2/3 = 4 3/6 + 2 4/6 = 7 1/6
3) 5 11/12 : 7,1 = 71/12 : 71/10 =
=71/12 * 10/72= 10/12= 5/6
4)7 1/6 : 4 3/10 = 43/6 * 10/43 = 10/6 = 5/3= 1 2/3
