determine:
a) -33-(-5)
b)-55/11
c)50-(-25)•(-3)
d)-54/4+17•5-144
e)-1/5+6/7
f)3/15/6/4​

Answer 1

Explicação passo-a-passo:

a) -33-(-5)

-33+5 = 28

b)-55/11

-(55÷11)

-(5)

-5

c)50-(-25)•(-3)

50+25×(-3)

50-75

-25

d)-54/4+17•5-144

-13,5+85-144

-157,5+85

-72,5

e)-1/5+6/7

$- \frac{1}{5} + \frac{6}{7} \\ \frac{ - 7 + 30}{35} \\ \frac{23}{35}$

f)3/15/6/4

$\frac{3}{15} \times \frac{1}{6} \times \frac{1}{4} \\ \frac{1}{5} \times \frac{1}{6} \times \frac{1}{4} \\ \frac{1}{120}$
