brilliants [131]

Answer:

$1\frac{1}{15}$

Step-by-step explanation:

$\frac{7}{5}+\frac{2}{3}-1\\$

Convertir elemento a fracción: 1 = 1/1

$=-\frac{1}{1}+\frac{7}{5}+\frac{2}{3}$

Mínimo común múltiplo de 1,5,3 = 15

Ajustar fracciones según el mcm

$=-\frac{15}{15}+\frac{21}{15}+\frac{10}{15}$

Dado que los denominadores son iguales, combine las fracciones:

$\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\\\\= \frac{-15+21+10}{15}\\\\$

Sumar Restar los números: -15 + 21 + 10 = 16

$=\frac{16}{15}\\\\16\div 15 = 1 \: remainder 1\\\\=1\frac{1}{15}$
