me ajuda aí PLS (ﾟ∀ﾟ)​

Answer 1

Resposta:

a)12

b)13

c)1,2

d)9,5

e)22

f)4

Explicação passo-a-passo:

a) $\frac{7}{1} +\frac{15}{3} =\frac{21+15}{3} = \frac{36}{3} = 12$

b) $\frac{10}{2} + \frac{8}{1} = \frac{10+16}{2} = \frac{26}{2} =13$

c) 3.7 - 2.5 = 1,2

d)$\frac{45}{10} + \frac{10}{2} = \frac{45 + 50}{10} = \frac{95}{10} = 9,5$

e) $\frac{20}{10} + \frac{20}{1} = \frac{20 + 200}{10} = \frac{220}{10} = 22$

f) $\frac{16}{4} : \frac{2}{2} = \frac{16}{4} * \frac{2}{2} = \frac{32}{8} = 4$
