Hi guys! Can you guys help me I forgot what this is :)

Explanation:

Point A is located at 0.3; each tickmark represents 0.1

0.3 as a fraction is 3/10 because 3 is in the tenths decimal place. This doesn't reduce.

Point B is at 0.4 which converts to 4/10 and then that reduces to 2/5. Divide both parts of 4/10 by 2 to get to 2/5

Point C is at 0.9 which converts to 9/10. That's as simplified as that fraction gets.

Point D is at 0.7 so it becomes 7/10. That doesn't reduce either.

answer: 2530

hope this
