Introduction to Fraction

The word fraction is derived from the Latin word "Fractus" means broken. Represents the total component, which includes the number of equal parts out of a whole.

Representation of Fractions

A fraction is represented by 2 more than one number, separated by a line. The number above is a numerator and the number below is a denominator. Example: 64 which means 6 out of 4 equal divisions.

Multiplication of Fractions

Multiplying a fraction by a whole number:

Example 1: 7 × (1/2) = 7/2

Example 2: 5 × (4/45) = 20/45, Dividing a number by a denominator by 5, we get 7/9

Fraction multiplication by fraction is actually a numerical product / product of denominators.

Solved Examples

Q1. If x= 9/11 and y= 4/15, then the value of x - y is

1. 5/165
2. 36/165
3. 91/165
4. 98/165

Ans. Correct answer is 4

x-y = 9/11 - 4/15

= 135-44/165

= 91/165

Q2. Reciprocal of 7 is

1. -7
2. 1
3. 7
4. 1/7

Q3. If the cost of 12 bananas is Rs 26.50, then the cost of 6 such bananas will be

1. Rs 10.50
2. Rs 12
3. Rs 13.25
4. Rs 20

Ans. Correct answer is 3

Given, the cost of 12 bananas = Rs 26.50 The cost of 1 banana = Rs 26.50/12

Therefore, the cost of 6 bananas = Rs (26.50/12) x 6

= Rs 13.25.

Q4. If the side of a square is 12.5 cm, then the area of square will be

1. 156.25 cm²
2. 160 cm²
3. 173.5 cm²
4. 180 cm²

Ans. Correct answer is 1

Given, side of a square = 12.5 cm

Area of square = side x side = 12.5 x 12.5 cm²

= 156.25 cm².

Q5. Product of 0.04 x 1.1 is

1. 0.044
2. 0.44
3. 4.04
4. 4.4

Ans. Correct answer is 1

0.04 x 1.1 = 0.044.

Q6. Decimal form of 15 rupees 5 paise is

1. Rs 15
2. Rs 15.5
3. Rs 155.0
4. Rs 15.05

Ans. Correct answer is 4

Q7. The value of 4kg 625g in gm will be

1. 4.620 g.
2. 4625 g
3. 40625 g
4. 400625 g

Ans. Correct option is 2

4kg 625g = 4 kg + 625 g

= (4 x 1000 + 625) g [1kg=1000g]

= (4000 + 625) g

= 4625 g

Q8. If the length of a rectangle is 7.1 cm and its breadth is 2.5 cm, then the area of rectangle will be

1. 4.6 cm²
2. 4.8 cm²
3. 8.875 cm²
4. 17.75 cm²

Ans. Correct Answer is 4

Area of rectangle = length x breadth

= 7.1 cm x 2.5 cm

= 17.75 cm²

Q9. If a car covers a distance of 95.5 km in 2.5 hours, then the average distance covered by it in 1 hour will be

1. 38 km
2. 38.2 km
3. 38.3 km
4. 39 km

Ans. Correct option is 1

Distance covered by the car = 95.5 km

And, the time required to cover this distance = 2.5 hours

Therefore, distance covered by it in 1 hour = 95.5/2.5 = 955/25

= 38.2 km

Q10. If we shift the decimal point two places towards right of a number 0.045, then the new number is

1. 0.0045
2. 4.5
3. 45
4. 450

Ans. Correct option is 2

Shifting the decimal points two places towards right of 0.045 means 0.045 x 100, which gives the number 4.5.
