Aiden, Anika, and Scarlett are having a friendly competition to see who can plot the decimal, 0.2, on a number line the fastest. Who will have an easier time if they plot it closer to 0.25 or 0?

• 0

• 0.25

Answer explanation

When you are looking between the points of 0 and 0.25 on the number line, 0.2 will be closer to 0.25.

Evelyn and Daniel are having a friendly debate. Evelyn thinks that graphing a decimal ordered pair, like (0.3, 0.6), is the same as graphing a normal ordered pair, like (3, 6). Daniel isn't so sure. Who do you think is right?

• Team Evelyn! Yes, it's the same.

• Team Daniel! No, it's not the same.

Answer explanation

Yes, it would be because graphing decimal numbers is the exact same thing as graphing whole numbers.

Plot these points on the number line:

0.1

0.2

0.4

0.7

0.9

Plot these points on the number line:

0.85

0.15

0.3

0.65

Plot these points on the number line:

0.75

When trying to plot 0.35 on the number line, will it be closer to 0.25 or 0.5?

• Closer to 0.5

• Closer to 0.25

Answer explanation

When trying to plot, you should round up the number. 0.35 will be much closer to 0.5 than 0.25
