Worksheet 4 of 30 (13% complete)

Question 1

A value decreases by 47% and then increases by 35%. What is the net percentage change?
Step 1: decrease by 47% → multiply by 0.53
Step 2: increase by 35% → multiply by 1.35
Net change = -28.4%
percentage, reasoning

Question 2

Which two numbers should be interchanged to make the equation 10 - 7 × 3 = 38 correct?
balance, interchange

Question 3

Which two numbers should be interchanged to make the equation 9 - 8 × 7 = 23 correct?
balance, interchange

Question 4

Simplify: (3 ÷ 11) - (9 - 10) × 2
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 2.27
bodmas, complex

Question 5

What operator should replace '?' to make 13 ? 5 × 4 = 35?
The correct operator is None because 13 None 5 × 4 = 35
operator, reasoning

Question 6

Find the missing number in the sequence: 2, 4, 8, ?, 32, 64
The pattern: Each term increases by 2. Therefore, the missing number is 16
pattern, sequence

Question 7

If % means ÷, # means -, $ means ×, @ means +, then find the value of 18 % 10 $ 11
Substitute symbols: 18 ÷ 10 × 11 = 19.8
substitution, basic

Question 8

Simplify: (1/3 + 7/4) + 8/8
Following BODMAS, calculate step by step to get 37/12
fractions, bodmas

Question 9

A value increases by 46% and then increases by 11%. What is the net percentage change?
Step 1: increase by 46% → multiply by 1.46
Step 2: increase by 11% → multiply by 1.11
Net change = 62.1%
percentage, reasoning

Question 10

What operator should replace '?' to make 6 ? 3 - 11 = 90?
The correct operator is None because 6 None 3 - 11 = 90
operator, reasoning

Question 11

If @ means +, # means -, $ means ×, % means ÷, then find the value of 7 # 12 % 4
Substitute symbols: 7 - 12 ÷ 4 = 4
substitution, basic

Question 12

What operator should replace '?' to make 19 ? 2 + 8 = 93?
The correct operator is None because 19 None 2 + 8 = 93
operator, reasoning

Question 13

Simplify: (6 × 7) × (14 + 12) × 8
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 8736
bodmas, complex

Question 14

If @ means +, % means ÷, $ means ×, # means -, then find the value of 8 $ 2 # 9
Substitute symbols: 8 × 2 - 9 = 7
substitution, basic

Question 15

What operator should replace '?' to make 15 ? 12 × 11 = 96?
The correct operator is None because 15 None 12 × 11 = 96
operator, reasoning

Question 16

A value decreases by 15% and then decreases by 15%. What is the net percentage change?
Step 1: decrease by 15% → multiply by 0.85
Step 2: decrease by 15% → multiply by 0.85
Net change = -27.8%
percentage, reasoning

Question 17

Simplify: 7/4 + (9/5 + 6/2)
Following BODMAS, calculate step by step to get 131/20
fractions, bodmas

Question 18

Simplify: (14 + 2) + (4 ÷ 10) ÷ 15
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 16.03
bodmas, complex

Question 19

Given # means -, @ means +, $ means ×, % means ÷, which symbols should be interchanged to make 14 # 10 $ 15 % 13 = 80?
The equation is already correct or no single interchange works
interchange, complex

Question 20

Simplify: (7/5 + 3/2) ÷ 8/5
Following BODMAS, calculate step by step to get 29/16
fractions, bodmas
