Let’s go step by step to solve each part of the worksheet.
---
Part 1: State the opposite of each number shown.
The “opposite” of a number means the same distance from zero on the number line, but on the other side. So:
- Opposite of -3 →
+3
- Opposite of 42 →
-42
- Opposite of 38.7 →
-38.7
- Opposite of -1¾ →
+1¾ (or +1.75)
- Opposite of -1,230 →
+1,230
- Opposite of 8,116.13 →
-8,116.13
✔ Answers:
a. 3
b. -42
c. -38.7
d. 1¾ or 1.75
e. 1,230
f. -8,116.13

Part 2: State the absolute value of each number.
Absolute value means how far a number is from zero — always positive (or zero).
- |−6| =
6
- |810| =
810
- |−49| =
49
- |−7.91| =
7.91
- |97¼| =
97¼ (or 97.25)
- |−2,000| =
2,000
✔ Answers:
g. 6
h. 810
i. 49
j. 7.91
k. 97¼ or 97.25
l. 2,000

Part 3: Circle the correct answer for each.
We compare numbers and their opposites or values.
m. Which is greater? the opposite of -4 OR |5|
→ Opposite of -4 = +4
→ |5| = 5
→ 5 > 4 → circle
|5|
n. Which is less? the opposite of 17 OR |17|
→ Opposite of 17 = -17
→ |17| = 17
→ -17 < 17 → circle
the opposite of 17
o. Which is greater? the opposite of 1 OR 0
→ Opposite of 1 = -1
→ -1 < 0 → so 0 is greater → circle
0
p. Which is greater? the opposite of -2 OR the opposite of 2
→ Opposite of -2 = +2
→ Opposite of 2 = -2
→ 2 > -2 → circle
the opposite of -2
q. Which is less? 10 less than 0 OR the opposite of 12
→ 10 less than 0 = -10
→ Opposite of 12 = -12
→ -12 < -10 → circle
the opposite of 12
r. Which is less? |99| OR |98|
→ |99| = 99, |98| = 98 → 98 < 99 → circle
|98|
s. Which is greater? |-1,224| OR the opposite of -1,242
→ |-1,224| = 1,224
→ Opposite of -1,242 = +1,242
→ 1,242 > 1,224 → circle
the opposite of -1,242
✔ Final choices:
m. |5|
n. the opposite of 17
o. 0
p. the opposite of -2
q. the opposite of 12
r. |98|
s. the opposite of -1,242
