Q1. Which of the following fractions is equivalent to:
$$\frac{3}{4}$$
?
A) $$\frac{6}{8}$$
B) $$\frac{9}{12}$$
C) $$\frac{12}{16}$$
D) All of these
Answer:
All of these
Useful Formula for this Question:
Equivalent fractions are obtained by multiplying numerator and denominator by the same non-zero number.
Concept Behind This Question:
Students should identify equivalent fractions.
Step-by-Step Solution:
We know:
$$\frac{6}{8}=\frac{3}{4}$$
$$\frac{9}{12}=\frac{3}{4}$$
$$\frac{12}{16}=\frac{3}{4}$$
Therefore, all fractions are equivalent.
Hence, the correct answer is:
All of these
Exam Tip:
Equivalent fractions represent the same numerical value.
Q2. Simplify:
$$\frac{15}{18}-\frac{3}{18}$$
A) $$\frac{12}{18}$$
B) $$\frac{2}{3}$$
C) Both A and B
D) $$\frac{18}{18}$$
Answer:
Both A and B
Useful Formula for this Question:
$$\frac{a}{b}-\frac{c}{b}=\frac{a-c}{b}$$
Concept Behind This Question:
Students should subtract like fractions and simplify.
Step-by-Step Solution:
Given:
$$\frac{15}{18}-\frac{3}{18}$$
Subtract numerators:
$$=\frac{12}{18}$$
Simplify:
$$=\frac{2}{3}$$
Both fractions are equivalent.
Hence, the correct answer is:
Both A and B
Exam Tip:
Always reduce fractions to their simplest form.
Q3. Convert into decimal:
$$\frac{56}{100}$$
A) $$5.6$$
B) $$0.56$$
C) $$56.0$$
D) $$0.056$$
Answer:
$$0.56$$
Useful Formula for this Question:
$$\frac{a}{100}=0.ab$$
Concept Behind This Question:
Students should convert fractions into decimals.
Step-by-Step Solution:
Given:
$$\frac{56}{100}$$
Move the decimal point two places left.
$$\frac{56}{100}=0.56$$
Hence, the correct answer is:
$$0.56$$
Exam Tip:
Denominator
$$100$$
means two decimal places.
Q4. Find:
$$\frac{7}{15}\times\frac{5}{14}$$
A) $$\frac{35}{210}$$
B) $$\frac{1}{6}$$
C) Both A and B
D) $$\frac{7}{3}$$
Answer:
Both A and B
Useful Formula for this Question:
$$\frac{a}{b}\times\frac{c}{d}=\frac{ac}{bd}$$
Concept Behind This Question:
Students should multiply fractions and simplify.
Step-by-Step Solution:
$$\frac{7}{15}\times\frac{5}{14}$$
$$=\frac{35}{210}$$
Simplify:
$$=\frac{1}{6}$$
Both values are equivalent.
Hence, the correct answer is:
Both A and B
Exam Tip:
Use cancellation whenever possible before multiplication.
Q5. Add:
$$0.48+0.36$$
A) $$0.84$$
B) $$0.74$$
C) $$0.94$$
D) $$0.64$$
Answer:
$$0.84$$
Useful Formula for this Question:
Align decimal points before addition.
Concept Behind This Question:
Students should add decimal numbers correctly.
Step-by-Step Solution:
Given:
$$0.48+0.36$$
Adding:
$$0.48+0.36=0.84$$
Hence, the correct answer is:
$$0.84$$
