Measure the lines with small paper clips and then with a centimeter ruler. line 1, has 3 paper clips = 12 cm with ruler. line 2, has 2 paper clips = to 6 cm with a ruler. line 3 has 2 paper clips = 9 cm ruler. explain why each measurements require more centimeters than paper clips

Its because the paper clips used here are of same length (4cm long).

So the measurements of lines two and three need to be multiples of 4 to me measured accurately with the paper.

i.e Line two needs to be 6cm + 2cm = 8cm (eight is a muliple of 4)

Line three needs to be 9cm + 3cm = 12cm (twelve is a multiple of 4)

Step-by-step explanation:

Since line 1 has 3 paper clips and its 12cm in length, the size of the paper clips is 4cm.

Line 2 is 6cm long and will require two more centimeters to measured accurately by the 4cm-paper clips.

Line 3 is 9cm and will require three more centimeters to be measured accurately by the 4cm-paper clips.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
