c) 2,555... - 2/3
d) 1,5 + 3/4
e) 0,5 + 0,222 ...

Answer 1

a) 2,1
b) 0,844
c) 1, 88
d) 2, 25
e) 0, 72

Answer 2

a)
$2+0,1=2,1= \frac{21}{10}$

b)
$\frac{4}{9} + \frac{4}{10} = \frac{40+36}{90} = \frac{76}{90}= \frac{38}{45}$

c)
$2 \frac{5}{9} - \frac{2}{3}= \frac{23}{9}- \frac{2}{3} = \frac{23-6}{9} = \frac{17}{6}$

d)
$\frac{15}{10} + \frac{3}{4} = \frac{30+15}{20} = \frac{45}{20}= \frac{9}{4}$

e)
$\frac{5}{10} + \frac{2}{9} = \frac{45+20}{90} = \frac{65}{90} = \frac{13}{18}$
