sabendo que a 3 inteiros 1/4 - 5/3 e B1 2/3 - 16 calcule a + b

hoje​

Answer 1

Resposta:

Explicação passo-a-passo:

Temos que

$a=3\frac{1}{4}-\frac{5}{3}=>a=\frac{12+1}{4}-\frac{5}{3}=>a=\frac{13}{4}-\frac{5}{3}=>a=\frac{3.13-4.5}{12}=>a=\frac{39-20}{12}=>a=\frac{19}{12}$

$b=1\frac{2}{3}-16=>b=\frac{3+2}{3}-16=>b=\frac{5}{3}-16=>b=\frac{5-3.16}{3}=>b=\frac{5-48}{3}=>b=-\frac{43}{3}$

Assim, temos que

$a+b=\frac{19}{12}-\frac{43}{3}=>a+b=\frac{19-4.43}{12}=>a+b=\frac{19-172}{12}=>a+b=-\frac{153}{12}=>a+b=-\frac{51}{4}$
