Question 1 of 20
1. Question
$\{25\% \times 480 + 16.66\% \times 300\} \div 5 + \sqrt{225} = ?$
Correct
$\text{25% of } 480 = \frac{1}{4} \times 480 = 120$
$\text{16.66% of } 300 \approx \frac{1}{6} \times 300 = 50$
$120 + 50 = 170$
$170 \div 5 = 34$
$\sqrt{225} = 15$
$34 + 15 = \boxed{49}$Incorrect
$\text{25% of } 480 = \frac{1}{4} \times 480 = 120$
$\text{16.66% of } 300 \approx \frac{1}{6} \times 300 = 50$
$120 + 50 = 170$
$170 \div 5 = 34$
$\sqrt{225} = 15$
$34 + 15 = \boxed{49}$ -
Question 2 of 20
2. Question
$\{62.5\% \times 256 – 20\% \times 150\} \times 2 – 3^2 = ?$
Correct
$\text{62.5% of } 256 = \frac{5}{8} \times 256 = 160$
$\text{20% of } 150 = \frac{1}{5} \times 150 = 30$
$160 – 30 = 130$
$130 \times 2 = 260$
$3^2 = 9$
$260 – 9 = \boxed{251}$Incorrect
$\text{62.5% of } 256 = \frac{5}{8} \times 256 = 160$
$\text{20% of } 150 = \frac{1}{5} \times 150 = 30$
$160 – 30 = 130$
$130 \times 2 = 260$
$3^2 = 9$
$260 – 9 = \boxed{251}$ -
Question 3 of 20
3. Question
$\{(3/5 \times 250) + \sqrt{196}\} \div 2 + 4^2 = ?$
Correct
$\frac{3}{5} \times 250 = 150$
$\sqrt{196} = 14$
$150 + 14 = 164$
$164 \div 2 = 82$
$4^2 = 16$
$82 + 16 = \boxed{98}$Incorrect
$\frac{3}{5} \times 250 = 150$
$\sqrt{196} = 14$
$150 + 14 = 164$
$164 \div 2 = 82$
$4^2 = 16$
$82 + 16 = \boxed{98}$ -
Question 4 of 20
4. Question
$\bigl(40\% \times 360 + \sqrt[3]{216}\bigr) – \bigl(\frac{1}{6} \times 72\bigr) = ?$
Correct
$\text{40% of } 360 = \frac{2}{5} \times 360 = 144$
$\sqrt[3]{216} = 6$
$144 + 6 = 150$
$\frac{1}{6} \times 72 = 12$
$150 – 12 = \boxed{138}$Incorrect
$\text{40% of } 360 = \frac{2}{5} \times 360 = 144$
$\sqrt[3]{216} = 6$
$144 + 6 = 150$
$\frac{1}{6} \times 72 = 12$
$150 – 12 = \boxed{138}$ -
Question 5 of 20
5. Question
$\{83.33\% \times 420 \div 7 + \sqrt{144}\} \times 2 – 5^2 = ?$
