Answer 1

Answer:

1. 50-23.754

Step-by-step explanation:

2.84.5-27.84

Answer 2

Step-by-step explanation:

1. let the increased number be x

so, x+23.754=50

x=50-23.754

x=26.246

therefore, we need 26.754 to increased to 50.

2. let the decreased number be x

so, 84.5-x=27.84

-x=27.84-84.5

-x =-56.66

x=56.66

therefore we need 56.66 to decreased to 27.84
