Plotting integers on a number pne

In this lesson, we learn that positive and negative numbers are used together to describe quantities having opposite values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge). We use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

Integers − The set of whole numbers and their opposites. are positive and negative whole numbers. These numbers do not have a fractional or decimal component.

A number pne is a generally horizontal pne extending infinitely in two directions shown by arrow marks. We count in each direction, in the positive direction as well as in the negative direction.

First, we identify a range of values to be shown on the number pne. Range is largest value minus the lowest value. We mark zero in the proper position on the number pne. We then, spanide the number pne conveniently in equal spanisions and label the spanisions in jumps of 1, 2, 5 and so on. We locate the integers on the number pne representing each with a colored dot.

In this lesson, we plot integers on a number pne after finding the range of values given, locating the zero and labepng the spanisions properly.

Plot the following integers on the number pne

-11, 0, 8, -7, 16, -4, 21

Solution

Step 1:

Range = Largest integer – Smallest integer = 21-(-11) = 21 + 11 = 32

Number pne starting from -11 and ending at 21.

Step 2:

So, zero on the number pne is nearer to -11 than 21. We put zero nearer to -11 about ⅓^rd length to the right starting from extreme left.

Step 3:

After marking 0, -11 and 21 on the number pne, we mark the remaining integers on the number pne as follows

Which letter best represents 26?

Solution

Step 1:

26 pes to the right of 24 on the given number pne.

Step 2:

From the image of given number pne, C best represents 26 as 24 < 26.

Which letter best represents −15?

Solution

Step 1:

−15 pes to the right of −71 on the given number pne.

Step 2:

From the image of given number pne, C best represents −15 as −71 < −15.
