Question

4 1/8 -1,11=
0,125-1/9=
1 1/5-0,09=

Answer 1

4 1/8 - 1,11 = 4 1/8 - 1 11/100 = 4 125/1000 - 1 110/1000 = 3 15/1000 = 3 3/200

0,125 - 1/9 = 125/1000 - 1/9 = 1/8 - 1/9 = 9/72 - 8/72 = 1/72

1 1/5 - 0,09 = 1 1/5 - 9/100 = 1 20/100 - 9/100 = 1 11/100

Answer 2

4+1/8-1,11=4 +0,125-1,11=4.125-1.11=3.015
0,125-0,111=0.014
1+0,20-0,09= 1+0.11=1,11

Answer 3

A)4 1/8-1 11/100=33/8-111/100=3300/800-888/800=2415/800=3,015
b)0,125-1/9=125/1000-1/9=1125/9000-1001/9000=124/9000=72,59
c)1 1/5-0,09=6/5-9/100=120/100-9/100=111/100=1,11
