Answer 1

2. thickness of 1 books = 24mm

total thickness of 4books/1 sack = 24×4

= 96

hence the total thickness of the sack is 96

(note: they have given 6 sheet of paper info, just to confuse you) :) (in a question, pay attention to only the info u need to find the answer to, forget the other things they have mentioned)

1. (5/4)×[(4/3)÷(-6/5)] = [(5/4)×(4/3)]÷[(5/4)×(-6/5)]

distributive property

a(b+c) = a×b + a×c

hope this helps you ^_^
