Explicación paso a paso:
Problema 1
[tex]\frac{7(3+8)}{7} =\frac{77}{7}=11[/tex]
Problema 2
[tex]\frac{100}{(4)(5)}=\frac{100}{20}=5[/tex]
Problema 3
[tex]2.1-(3.5+2.1)+(5+3.5)=2.1-\frac{28}{5}+\frac{17}{2}=5[/tex]
Problema 4
[tex][20-(8-3)]-(9-4)=20-5-5=10[/tex]
Problema 5
[tex]3-(0.5)(2)+4=3-1+4=6[/tex]
Problema 6
[tex][(3+4)(5)]-5+(2)(5)=[(7)(5)]-5+10=35-5+10=40[/tex]
Problema 7
[tex]4.6+[20.7-(11.6+9.1)]=4.6+20.7-\frac{207}{10}=\frac{23}{5}[/tex]
