Answer 2

Step-by-step explanation:

1. -4/9×3/5×(-9/10)

sol:-6/25

2.-33/9-(-11/12)

sol:-33/9+11/12

lcm of denominators = 36

= -33×4+11×3/36

= -99/36

=-11/4

3.(3.65-2.65)×1000

= 1×1000

=1000

4.sol:

lcm of denominators = -84

2×-28/-84;-3×-42/-84;4×12/-84;7×-21/-84

= -56/-84;126/-84;48/-84;-147/-84

A.O:-147/-84<-56/-84<48/-84<126/-84

5.5×[25+{(-4)×16-8÷2}]

sol:5×[25+{(-4)×16-4}]

= 5×[25+{(-4)×12}]

= 5×[25+{-48}]

= 5×[25-48]

= 5×[-23]

= -115

I HOPE IT MAY HELPS YOU!

HAVE A NICE DAY!

THANK YOU!
