16 similar writing pads and 24 similar jotter books are stacked in a pile. their total thickness is 14.4cm.Each writing pad is 3x as thick as each jotter book. what is the thickness of the pile of jotter books?
Thickness of jotter book = x, of pad = 3x
24x + 16(3x) = 14.4
Solve for x.
Sorry, i need to solve this by a non-algebraic way as we have not learnt algebra yet. Can you show me how? Tks.
To find the thickness of the pile of jotter books, we need to determine the thickness of one jotter book first. Let's represent the thickness of one jotter book as "x" cm.
Given that each writing pad is 3 times as thick as each jotter book, the thickness of one writing pad would be 3x cm.
So, the total thickness of the pile can be represented as:
16 writing pads * (3x cm) + 24 jotter books * (x cm) = 14.4 cm
Now, let's solve the equation:
48x + 24x = 14.4
Combining like terms:
72x = 14.4
Dividing both sides by 72:
x = 14.4 / 72
x = 0.2 cm
Therefore, the thickness of one jotter book is 0.2 cm.
