Question

Can someone help me with questions 20 and 21? Questions 21 has part A and B by the way! I’ll appreciate the help!

Answer 1

Answer:

1) 68+28 = 96 cards

2) 278.32 - 3698 is a question that gives a negative answer

   We rewrite as;

    278.32

-  3698,00 =  see 78.32 - 98.00 turns to -19.68 and 200 - 3600 = -3400

 -  3400 -+19.68 = -  3419.68

We add the last bit as it is the remainder of 3400 if done separately.

2b) With adding both numbers  278..32 + 3698 = 3976.32
