Question

Bardzo proszę o pomocy....

Answer 1

Answer:

N1

a) 0,9

b) 1,12

c) 0,8

N2

$a)0,15=\frac{15}{100}=\frac{3}{20}\\b)5,4=\frac{54}{10}=\frac{27}{5}=5\frac{2}{5}\\c)0,032=\frac{32}{1000}=\frac{4}{125}$

N3

$a)3\frac{3}{8}+1\frac{1}{8} =4\frac{4}{8} =4,5\\b)\frac{3}{10} *\frac{5}{6} = \frac{1}{4} =0,25\\c)\frac{14}{15} :\frac{7}{10} =\frac{14}{15}*\frac{10}{7}=\frac{4}{3}\\d)1,2+\frac{3}{4}=\frac{12}{10}+\frac{3}{4}=\frac{39}{20}=1,95\\e)7\frac{3}{5}-0,8=7,6-0,8=6.8$
