Деление- это дробью или нет?

Answer 1

1)1/20+24/100=5/100+24/100=29/100
2)29/100*8 1/3=29/100*25/3=29/12=2 5/12
3)2 5/12-1 1/6=2 5/12-1 2/12=1 3/12=1 1/4
4)3 5/6-1 2/15=3 25/30-1 4/30=2 21/30=2 7/10
5)2 7/10*5/9=27/10*5/9=3/2=1 1/2
6)1 1/4*2=5/4*2=5/2=2 1/2
7)1 1/2+2 1/2=4

Answer 2

1) 1/20 +24/100 = 5/100+24/100=29/100

2) 29/100* 8 1/3= 29/100 * 25/3 = 29/4 * 1/3=29/12=2 5/12

3)2 5/12 - 1 1/6 = 2 5/12 - 1 2/12 = 1 3/12 = 1 1/4

4) 3 5/6 -1 2/15 = 3 25/30 - 1 4/30 = 2 21/30 =2 7/10

5)2 7/10 * 5/9 = 27/10 * 5/9= 3/2*1/1=3/2

6)1 1/4 * 2=5/4 * 2=5/2

7)3/2 +5/2 =8/2=4
