Answer:
[tex]8 \frac{20}{25} \: or \: 8 \frac{4}{5} [/tex]
Step-by-step explanation:
[tex]7 \frac{3}{10} + 9 \frac{12}{15} = n[/tex]
convert them to improper fractions
[tex]7 \frac{3}{10} = \frac{73}{10} \\ 9 \frac{12}{15} = \frac{147}{15} [/tex]
then, add.
[tex] \frac{73}{10} + \frac{147}{15} \\ 73 + 147 = 220 \\ 10 + 15 = 25[/tex]
[tex]so \: you \: get \: \frac{220}{25} [/tex]
[tex]now \: convert \: it \: into \: a \: mixed \: number[/tex]
[tex] \frac{220}{25} = 8 \frac{20}{25} \\ lowest \: term: 8 \frac{4}{5} [/tex]
