Step-by-step explanation:
[tex] \\ \bf1) \: \: 4 \frac{1}{8} + \frac{2}{8} [/tex]
[tex] \\ \bf = \frac{33}{8} + \frac{2}{8} [/tex]
[tex] \\ \bf = \frac{33 + 2}{8} [/tex]
[tex] \\ \bf = \frac{35}{8} [/tex]
[tex] \\ \bf = 4\frac{3}{8} [/tex]
[tex] \\ \bf2) \: \: 8\frac{4}{16} + \frac{12}{16} [/tex]
[tex] \\ \bf = \frac{132}{16} + \frac{12}{16} [/tex]
[tex] \\ \bf = \frac{132 + 12}{16} [/tex]
[tex] \\ \bf = \frac{144}{16} [/tex]
[tex] \\ \bf = 9[/tex]
[tex] \\ \bf3) \: \: 2 \frac{65}{100} + \frac{91}{100} [/tex]
[tex] \\ \bf = \frac{265}{100} + \frac{91}{100} [/tex]
[tex] \\ \bf = \frac{265 + 91}{100} [/tex]
[tex] \\ \bf \ = \frac{356}{100} [/tex]
[tex] \\ \bf = 3.56[/tex]
[tex] \\ \bf4) \: \: 4 \frac{14}{40} + \frac{36}{40} [/tex]
[tex] \\ \bf = \frac{174}{40} + \frac{36}{40} [/tex]
[tex] \\ \bf = \frac{174 + 36}{40} [/tex]
[tex] \\ \bf = \frac{210}{40} [/tex]
[tex] \\ \bf = 52 \frac{2}{4} [/tex]
