Question

2 Całe i 1/3+3/4:12=


1/3 razy (3/5-3/10)=


4 Całe i 1/5:7/10-5 Całych i 3/4

Answer 1

2 1/3+3/4:1/2=2 1/3+3/4·2=2 1/3+3/2=2 1/3+1 1/2=3 2/6+3/6=3 5/6

1/3×(3/5-3/10)=1/3×(6/10-3/10)=1/3×3/10=1/10

4 1/5:7/10-5 3/4=21/5×10/7-5 3/4=6-5 3/4=1 1/4

Answer 2

2 całe i 1/3 + 3/4 : 12 = 7/3 + 3/4 * 1/12 = 7/3 + 3/48 = 112/48 + 3/48 = 115/48 = 2 całe 19/48

1/3 * (3/5 - 3/10) = 1/3 * (6/10 - 3/10) = 1/3 * 3/10 = 3/30 = 1/10

4 całe i 1/5 : 7/10 - 5 całych i 3/4 = 21/5* 10/7 - 23/4 = 210/35 - 23/4 = 840/140 - - 805/140 = 35/140 = 1/4
