Simplify and find the value

a)(-12)+32+(-25)
b)(-65)-(-18)
c)(-153) × (-110)
d)(-280)÷7
e)2 5/6 + 3 7/8
f)4 2/10 - 2 3/5

Answer 1

1/-18,-5,-47,16830,-40,6 17/24, 1 3/5

Step-by-step explanation:

A multiplicative inverse of a number is a rational number which being multiplied by the number gives 1. So here the multiplicative inverse of -18 is 1/-18.

Simplify and find the value.

a)(-12)+32+(-25)

=-12 +32 - 25

=-12-25+32

=-37+32

=-5

b)(-65)-(-18)

=-65 + 18

=-47

c)(-153)×(-110)=16380

e) 2 5/6 + 3 7/8

= 17/6+31/8

= 68+93/24

=161/24

= 6 17/24

f)4 2/10-2 3/5

= 42/10- 13/5

= 42-26/10

= 16/10

= 8/5

=1 3/5
