Test: Working with Fractions - Class 7 MCQ

Total number of blocks = 8
Number of shaded blocks = 1
Number of unshaded blocks = 7
⇒ Fraction of Shaded area =  No. of shaded blocks/ Total number of blocks = 1/8.
Thus, the correct answer is Option B.

A mixed fraction is a fraction formed by combining a whole number and a proper fraction.

Thus, the correct Option B.

(1/2) x (1/5) = 1/10

Multiply both numerators and denominators.


Thus, the correct answer is Option B.

Apala ate 3/5 of an orange.

The remaining part was eaten by Meenu.

• Total orange: 5/5
• Portion eaten by Apala: 3/5
• Remaining portion: 5/5 - 3/5 = 2/5

Therefore, Meenu ate 2/5 of the orange.

5 ÷ 5/2 is equal to:

To solve this problem, follow these steps:

• First, understand that dividing by a fraction is equivalent to multiplying by its reciprocal.
• Therefore, 5 ÷ 5/2 can be rewritten as 5 × 2/5.
• Next, simplify the expression:
  • Multiply: 5 × 2 = 10.
  • Then divide: 10 ÷ 5 = 2.

The final answer is 2.

- To convert 0.23 into a fraction, recognize the decimal represents 23 hundredths.
- This means 0.23 is equivalent to 23/100.
- The fraction 23/100 is already in its simplest form because 23 is a prime number and has no common factors with 100 other than 1.
- Therefore, the correct answer is option C: 23/100.

Area = Length × Width = (3/4) × (1/2) = 3/8 square units.

This illustrates how to multiply fractions to find the area of a rectangle.

To find the amount in each cup:

Total amount = 3/4 liter ÷ 3 = (3/4) × (1/3) = 1/4 liter.

This illustrates the concept of division with fractions in practical applications.

To multiply fractions, multiply the numerators and then the denominators:

(5 × 7) / (12 × 18) = 35 / 216.

This reinforces the rule of multiplying fractions through straightforward calculations.

The multiplication results in: (1/4) × (1/2) = 1/8.

This problem emphasizes the idea of finding a part of a fraction through multiplication.

Distance = Speed × Time = 60 km/h × 1/4 h = 15 km.

This illustrates the direct application of the distance formula with a fraction of time.

To find 3/4 of 2/5, multiply the two fractions:

(3/4) × (2/5) = 6/20, which simplifies to 3/10.

This question emphasizes the multiplication of fractions and simplification of the result.

When multiplying two fractions that are both less than 1, the result will always be less than either of the fractions. This is a key property of fractional multiplication.
