To solve this problem, we would be needing the actual
height or size of the book which is not given in the problem. However for the
sake of calculation let us assume that the average height of a book is 8.5 inches.
Then the next step we have to do is to convert the height
of the first grader from units of meter to units of inches. We know that:
1 meter = 39.37 inches
Therefore the height of the first grader is 39.37 inches.
Taking the ratio with the bigger number in the numerator
(height of the 1st grader / height of the book):
ratio = 39.37 inches / 8.5 inches
ratio = 4.63
Therefore this means that the first grader is about 4.63
times taller than the book.
