Me to answer these you in advance. 1 - a string is cut into three pieces in the ratio 5 : 4 : 2. if the longest piece of string is 87 cm longer than the shortest piece of string, find the length of the string before it is being cut. = 2- a bookstore sold fiction books, textbooks and workbooks last month in the ratio 6 : 5 : 9 respectively. if the store sold 1350 workbooks, what was the total number of fiction books and textbooks sold that month? ? =

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

the answer is 40.
