Question

On Saturday, Craig rode his bike 5/8 of a mile. On Sunday, he rode his bike 1/2 of a mile. Craig added 5/8 + 1/2 to find the total distance, in miles, he rode his bike on the two days. Craig said 5/8 + 1/2 = 6/10 and plotted 6/10 on this number line.
* Explain why Craig's answer is not responsible.
* Find the total distance, in miles, Craig rode on his bike Saturday and Sunday.
* Explain how to use the number line to show your answer is correct.

Answer 1

Hi there!

Craig's reason is not reasonable because when you add fractions you have to find equivalent fractions.

The total distance in miles would be 1 1/8 miles.

By using a number line, line up the fractions, so then you could add them both.

Hope this helps :)
