Mr. Maddox asked four students to create a number line to help find the sum of the fractions.

Negative StartFraction 7 over 10 EndFraction + StartFraction 4 over 10 EndFraction

Which number line would be best to find this sum?
A number line going from Negative StartFraction 8 over 10 EndFraction to 0 in increments of StartFraction 1 over 10 EndFraction

A number line going from Negative StartFraction 3 over 10 EndFraction to positive StartFraction 3 over 10 EndFraction in increments of StartFraction 1 over 10 EndFraction

A number line going from StartFraction 4 over 10 EndFraction to StartFraction 11 over 10 EndFraction in increments of StartFraction 1 over 10 EndFraction

A number line going from 0 to StartFraction 15 over 10 EndFraction in increments of StartFraction 1 over 10 EndFraction

A

Because you need to start at -7/10 and move right 4/10 to reach -3/10. The number line from -8/10 to 0 includes both -7/10 and -3/10, so choice A is best.
