    3/4-3/10=30/40-12/40=18/40
    3/2\times5/6=15/12=5/4
    7/8:1=7/8\times1/1=7/8
    2/5+5/6\times8/5=2/5+4/3=6/15+20/15=26/15
    6/7:9/17-1=6/7\times17/9-1=34/21-1=34/21-21/21=13/21

    3/4 – 3/10 = 30/40 – 12/ 40 = 18/40
    3/2 x 5/6 = 15/12 = 5/4
    7/8 : 1 = 7/8 x 1/1 = 7/ 8
    2/5 + 5/6 x 8/5 = 2/5 + 4/3 = 6/15+ 20/15= 26/15
    6/7 : 9/17-1= 6/7 x 17/9 -1 = 34/21 – 1 = 34/21 – 21/21=13/21
