**Rational and Irrational Numbers | Practice set 1.2**

**1. Compare the following numbers**.

(1) -7, -2

**Explanation :**

➥ To Compare the two numbers we use the symbols <, =, >. (‘<‘ : Less than, ‘=’ : Equal and ‘>’ : Greater than)

➦ To Compare the two numbers, first identify the numbers if positive or negative.

➥ As we saw in the previous section that on a number line, positive numbers are on the right side of the ‘0’ (zero) and negative numbers are on the left side.

➦ Numbers are increases towards the right side and decrease on the left side of the zero.

➥ So -2 is greater than -7

**Ans : ** ∴ -7 < -2.

**Explanation :**

➠ Zero ‘0’ is always greater than negative numbers.

➠ Positive numbers are always greater than negative numbers.

**Explanation :**

➠ Positive numbers are always greater than 0.

**Explanation : **
➠ Positive numbers are always greater than negative numbers .

**Explanation : **
➠ 40 is less than 141 so.

**Explanation : **
➠ −17 is less than − 13 so.

**Ans : ** |
15 | = |
15 × 4 | = |
60 | ; |

12 | 15 × 4 | 48 |

** ** |
7 | = |
7 × 3 | = |
21 | ; |

16 | 16 × 3 | 48 |

Now 60 is greater than 21 so :

**Explanation : **
While comparing two fractions we have to check following points
➥ Check the fraction is positive or negative.

➠ Then check the denominator is equal or not.

➥ If denominator is equal then compare with numerator number.

➠ If denominator is not equal then make it equal by multiplying or devising.

**Ans : ** | −7 | = |
−7 × 4 | = − |
28 | , |

11 | 11 × 4 | 44 |

−3 | = |
−3 × 11 | = − |
33 | , |

4 | 4 × 11 | 44 |
