Question

Beatrice threw a stone one and seven fourteenths yards. Tilly threw a stone nine fourteenths of a yard. What is a reasonable estimate of the difference between their two throws?

1 yard
one and one half yards
2 yards
two and one half yards

Answer 1

The answer would be 1 yards because 1 and 7/14 minus 9/14 is 12/14 which rounds to 1 yard

Answer 2

1 yard

Explanation:

7/14 is 1/2 while 9/14 is greater than 1/2 but a lot less than a whole. So a strong estimate would assume that it is (1 1/2)-(1/2) for the approximate difference in their throws were
