Fractions Practice Questions
Fractions represent parts of a whole. These fractions practice problems will help you understand how to add, subtract, multiply, and divide fractions.
Question 5: Add $\frac{1}{4} + \frac{3}{8}$.
Answer: $\frac{5}{8}$
Explanation: To add fractions, find a common denominator. The common denominator for 4 and 8 is 8. $\frac{1}{4} = \frac{1 \times 2}{4 \times 2} = \frac{2}{8}$ Now, $\frac{2}{8} + \frac{3}{8} = \frac{2+3}{8} = \frac{5}{8}$.
Question 6: Subtract $\frac{2}{3} - \frac{1}{6}$.
Answer: $\frac{1}{2}$
Explanation: The common denominator for 3 and 6 is 6. $\frac{2}{3} = \frac{2 \times 2}{3 \times 2} = \frac{4}{6}$ Now, $\frac{4}{6} - \frac{1}{6} = \frac{4-1}{6} = \frac{3}{6} = \frac{1}{2}$.
Question 7: Multiply $\frac{3}{5} \times \frac{10}{9}$.
Answer: $\frac{2}{3}$
Explanation: Multiply the numerators and the denominators, then simplify. $\frac{3}{5} \times \frac{10}{9} = \frac{3 \times 10}{5 \times 9} = \frac{30}{45}$ Simplify by dividing both by 15: $\frac{30 \div 15}{45 \div 15} = \frac{2}{3}$.
Question 8: Divide $\frac{4}{7} \div \frac{2}{14}$.
Answer: $4$
Explanation: To divide by a fraction, multiply by its reciprocal. $\frac{4}{7} \div \frac{2}{14} = \frac{4}{7} \times \frac{14}{2} = \frac{4 \times 14}{7 \times 2} = \frac{56}{14} = 4$.
Decimals Practice Questions
Decimals are another way to represent parts of a whole. These decimals practice problems will cover basic operations with decimal numbers.
Question 9: Add $12.35 + 7.8$.
Answer: $20.15$
Explanation: Align the decimal points and add.
12.35
+ 7.80
-------
20.15
Question 10: Subtract $25.6 - 13.25$.
Answer: $12.35$
Explanation: Align the decimal points and subtract.
25.60
- 13.25
-------
12.35
Question 11: Multiply $3.5 \times 2.4$.
Answer: $8.4$
Explanation: Multiply as whole numbers, then place the decimal point based on the total number of decimal places in the factors. $3.5 \times 2.4 = 8.40$
Question 12: Divide $10.8$ by $0.9$.
Answer: $12$
Explanation: Move the decimal point in the divisor and dividend to make the divisor a whole number. $10.8 \div 0.9 = 108 \div 9 = 12$.
Basic Algebra Practice Questions
Algebra introduces variables and equations. These basic algebra problems will help you solve for unknown values.
Question 13: Solve for $x$: $x + 7 = 15$.
Answer: $x = 8$
Explanation: Subtract 7 from both sides of the equation. $x + 7 - 7 = 15 - 7$ $x = 8$
Question 14: Solve for $y$: $3y = 21$.
Answer: $y = 7$
Explanation: Divide both sides of the equation by 3. $\frac{3y}{3} = \frac{21}{3}$ $y = 7$
Question 15: Solve for $z$: $\frac{z}{4} = 5$.
Answer: $z = 20$
Explanation: Multiply both sides of the equation by 4. $\frac{z}{4} \times 4 = 5 \times 4$ $z = 20$
Question 16: Solve for $a$: $2a - 5 = 11$.
Answer: $a = 8$
Explanation: 1. Add 5 to both sides: $2a - 5 + 5 = 11 + 5 \implies 2a = 16$. 2. Divide both sides by 2: $\frac{2a}{2} = \frac{16}{2} \implies a = 8$.
