Question

Find the number halfway between 3/5 and 7/10 .

27/40

2/3

7/10

13/20

Answer 1

what you think>?

Answer 2

Have you considered the average?

\(\dfrac{\dfrac{3}{5}+\dfrac{7}{10}}{2}\)

Have you considered getting a matching denominator:

\(\dfrac{3}{5}\;vs\;\dfrac{7}{10}\;suggests\;\dfrac{6}{10}\;vs\;\dfrac{7}{10}\;or\;\dfrac{12}{20}\;vs\;\dfrac{14}{10}\)

Now, WHY would I go to the trouble to do the 20ths?

Answer 3

Of course, you meant to write \(\dfrac{14}{20} \), not \(\dfrac{14}{10} \).

Answer 4

Right. I fixed that twice. I guess it took three.
