It looks like you've uploaded an
answer key for a math worksheet titled
"Inequalities Sheet 4:2 Answers" from
Math-Salamanders.com. This sheet contains 20 problems where students are asked to compare two mathematical expressions using inequality symbols (<, >, or =).
However, since this is the
answer key, it already shows:
- The two expressions to compare.
- The calculated values of each expression (in red).
- The correct inequality symbol between them.

🔍 Let's go through how to solve one of these problems step-by-step to understand the method.
Take
Problem 1 as an example:
> 1) 5 × 9 < 23 × 2
> = 45 = 46
#### Step-by-step:
1. Calculate the left side:
$ 5 \times 9 = 45 $
2. Calculate the right side:
$ 23 \times 2 = 46 $
3. Compare the results:
$ 45 < 46 $ → So, use
<
✔ Therefore, the correct symbol is
<, which matches the answer key.

🧠 General Strategy for These Problems:
For each problem:
1.
Evaluate both sides of the inequality.
2.
Compare the results:
- If left < right → use `<`
- If left > right → use `>`
- If left = right → use `=`
3. Fill in the blank with the correct symbol.

✔ Verification of a Few More Examples:
Let’s check
Problem 11:
> 11) 3 × 90 = 350 − 80
> = 270 = 270
- Left: $ 3 \times 90 = 270 $
- Right: $ 350 - 80 = 270 $
- Since both are equal → use `=`
✔

Problem 14:
> ½ of 250 < 20 × 7
> = 125 = 140
- Half of 250 = $ 250 ÷ 2 = 125 $
- $ 20 × 7 = 140 $
- $ 125 < 140 $ → Use `<`
✔
