1) (13/24)*6=13/4=3 1/4
2) (9/39)*(13/18)=1/(3*2)=1/6
3) (1 3/5):(2 2/15)=(8/3)*(15/32)=5/4=1 1/4
4) (1 2/5)*(1 3/7)=(7/5)*(10/7)=2
5) (7/17):21=1!/51
6) (9/35):(3/10)=(9/35)*(10/3)=3*2/7=6/7
Ответ:
Пошаговое объяснение:
А)
13/24 * 6 = 13/4 * 1 = 13/4 =
3. 1/4
Б)
1. 2/5 * 1. 3/7 = 7/5 * 10/7 = 10/5 = 2
В)
9/39 * 13/18 = 1/3 * 1/2 = 1/6
Г)
7/17 : 21 = 7/17 * 1/21 = 1/17 * 1/3 = 1/51
Д)
1. 3/5 : 2. 2/15 = 8/5 : 32/15 = 8/5 * 15/32 = 1/1 * 3/4 = 3/4
Е)
9/35 : 3/10 = 9/35 * 10/3 = 3/7 * 2/1 = 6/7
