porfa ayuden a resolver esto a.. 0.42 x 5 -7 = b.... -25 +34 x 6/3 = c..... -17/8 + 3 x 6= d... -3/5 x 8 + 5.25 = e..... -28 + 35 + 2.5 entre 1.5=

OPERAMOS:
a.0.42 x 5 -7 = primero la multiplicacion
2,1 - 7
-4,9
b. -25 +34 x 6/3 = primero la multiplicacion
-25+68
43
c. -17/8 + 3 x 6= primero la multiplicacion (la division es inexacta)
17/8+18
17+8(18)/8
161/8
d.-3/5 x 8 + 5.25 =
-24/5+125
601/5
e.-28 + 35 + 2.5 / 1.5=
28+35+5/3
63+5/3
194/3
