Question

a)0,125-1/9=

b)3 1/3-3,3=

c)1 1/5-0,09=

Answer 1

a) 1/8-1/9= 9/72-8/72=1/72

b) 10/3 - 33/10= 100/30-99/30=1/30

c) 6/5 - 9/100= 120/100-9/100= 111/100=1,11

Answer 2

a)\frac{1}{8}-\frac{1}{9}=\frac{9}{72}-\frac{8}{72}=\frac{1}{72}

b)3\frac{1}{3}3\frac{3}{10}=3\frac{10}{30}3\frac{9}{30}=\frac{100}{30}\frac{99}{30}=\frac{1}{30}

c)1\frac{1}{5}\frac{9}{100}=1\frac{20}{100}\frac{9}{100}=\frac{120}{100}\frac{9}{100}=\frac{111}{100}
