Question

1) 5/9+13/27= 2) 9/17-19/68= 3) 9/10+4/15= 4) 4/15-11/60= 5) 3/12+25/30=

Answer 1

1)5/9^*3 + 13/27= 15/27+13/27=28/27=1 1/27

2)9/17^*4 - 19/68 = 36/68 - 19/68= 17/68

3)9/10^*3 + 4/15*2 = 27/30 + 8/30 =35/30 = 1 5/30 = 1 1/6

4)4/15^*4-11/60 = 16/60 - 11/60 = 5/60 = 1/12

5) 3/12^*5 + 25/30^*2 = 15/60 + 50/60 = 65/60 = 1 5/60 = 1 1/12
