  6. Asked: In:

    Which of the following pairs represent the same rational numbers: -7/21 and 3/9?

    Garinder

    -7/21 and 3/9 ⇒ -7/21 = -1/3 and 3/9 = 1/3 ∵ -1/3 ≠ 1/3 ∴ -7/21 ≠3/9 Class 7 Maths Chapter 9 Exercise 9.1 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-7/maths/chapter-9/

    -7/21 and 3/9
    ⇒ -7/21 = -1/3 and 3/9 = 1/3
    ∵ -1/3 ≠ 1/3
    ∴ -7/21 ≠3/9

  7. Asked: In:

    The points P, Q, R, S, T, U, A and B on the number line are such that, TR = RS = SU and AP = PQ = QB. Name the rational numbers represented by P, Q, R and S.

    Garinder

    Each part which is between the two numbers is divided into 3 parts. Therefore, A= 6/3, P=7/3, Q=8/3 and B=9/3 Similarly T=-3/3, R=-4/3, S=-5/3 and U = -6/3 Thus, the rational numbers represented P, Q, R and S are 7/3, 8/3, -4/3 and -5/3 respectively.

  8. Asked: In:

    Give four rational numbers equivalent to: -2/7

    Garinder

    2/7 = -2x2/7x2 = -4/14, -2x3/7x3 = -6/21, -2x4/7x4 = -8/28, -2x5/7x5 = -10/35 Therefore, four equivalent rational numbers are -4/14, -6/21, -8/28, -10/35. Class 7 Maths Chapter 9 Exercise 9.1 for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-7/maths/chapter-9/

    2/7 = -2×2/7×2 = -4/14, -2×3/7×3 = -6/21, -2×4/7×4 = -8/28, -2×5/7×5 = -10/35
    Therefore, four equivalent rational numbers are -4/14, -6/21, -8/28, -10/35.

  9. Asked: In:

    Write four more rational numbers in each of the following patterns: -3/5, -6/10, -9/15,-12/20,….

    Garinder

    -3/5, -6/10, -9/15,-12/20,…. ⇒ -3x1/5x1, -3x2/5x2, -3x3/5x3, -3x4/5x4,......... Therefore, the next four rational numbers of this pattern would be -3x5/5x5, -3x6/5x6, -3x7/5x7, -3x8/5x8, = -15/25, -18/30, -21/35, -24/40 Class 7 Maths Chapter 9 Exercise 9.1 for more answers vist to: https://www.tiwarRead more

    -3/5, -6/10, -9/15,-12/20,….

    ⇒ -3×1/5×1, -3×2/5×2, -3×3/5×3, -3×4/5×4,………
    Therefore, the next four rational numbers of this pattern would be
    -3×5/5×5, -3×6/5×6, -3×7/5×7, -3×8/5×8, = -15/25, -18/30, -21/35, -24/40

  11. Asked: In:

    List five rational numbers between: -1 and 0

    Garinder

    (i) -1 and 0 Let us write -1 and 0 as rational numbers with denominator 6. ⇒ -1 = -6/6 and 0 = 0/6 ∴ -6/6 < -5/6 < -4/6 < -3/6 < -2/6 < -1/6 < 0 ⇒ -1 < -5/6 < -2/3 < -1/2 < -1/3 < -1/6 < 0 Therefore, five rational numbers between -1 and 0 would be -5/6, -2/3, -1/2Read more

    (i) -1 and 0
    Let us write -1 and 0 as rational numbers with denominator 6.
    ⇒ -1 = -6/6 and 0 = 0/6
    ∴ -6/6 < -5/6 < -4/6 < -3/6 < -2/6 < -1/6 < 0
    ⇒ -1 < -5/6 < -2/3 < -1/2 < -1/3 < -1/6 < 0

    Therefore, five rational numbers between -1 and 0 would be
    -5/6, -2/3, -1/2, -1/3, -1/6
