Answer:

(i)

Given, numbers are −1 and 0.

Write −1 and 0as a rational number with denominator 6.

Now, the rational number becomes,

−1=−66 and 0=06

Now, we write the number between −66 and 06.

−66<−56<−46<−36<−26<−16<06−1<−56<−46<−36<−26<−16<0−1<−56<−23<−12<−13<−16<0

Thus, the five rational number between −1 and 0 are −56,−23,−12,−13,−16.

(ii)

Given, number are −2 and −1.

Write −1 and 0as a rational number with denominator 6.

Now, the rational number becomes,

−2=−126 and −1=−66

Now, we write the number between −126 and −66.

−126<−116<−106<−96<−86<−76<−66−2<−116<−106<−96<−86<−76<−1−2<−116<−53<−32<−43<−76<−1

Thus, the five rational number between −2 and −1 are −116,−53,−32,−43,−76.

(iii)

Given that the rational number is −45 and −23.

Write −45 and −23as a rational number with denominator 45.

Now, the rational number becomes,

−4×95×9=−3645 and −2×153×15=−3045

Now, we write the number between −3645 and −3045.

−3645<−3545<−3435<−3345<−3245<−3145<−3045−45<−3545<−3435<−3345<−3245<−3145<−23−45<−79<−3435<−3345<−3245<−3145<−23

Thus, the five rational number between −45 and −23 are −79,−3435,−3345,−3245,−3145.

(iv)

Given, number are 12 and 23.

Write −12 and 23as a rational number with denominator 36.

Now, the rational number becomes,

1×182×18=1836 and 2×123×12=2436

Now, we write the number between 36 and 46.

1836<1936<2036<2136<2236<2336<243612<1936<59<712<1113<2336<23

Thus, the five rational number between −12 and 23 are 1936,59,712,1113,2336.

 

Question 2

Write four more rational numbers in each of the following patterns: (i) -3/ 5, -6/10, -9/15, -12/20 ,........... (ii)-1/4 ,-2/8, -3/12 ,..... (iii) -1/6,2/ -12,3/-18,4/-24,...... (iv)-2/3,2/-3,4/-6,6/-9,….

Answer:

(i)

Given, rational numbers are −35,−610,−915,−1220

The pattern of the above rational numbers is,

−35=−3×15×1,−610=−3×25×2,−915=−3×35×3,−1220=−3×45×4

The next four rational numbers according to above pattern are,

−3×55×5,−3×65×6,−3×75×7,−3×85×8−1525,−1830,−2135,−2440

(ii)

Given, rational numbers are −14,−28,−312.

The pattern of the above rational numbers is,

−14=−1×14×1,−28=−1×24×2,−312=−1×34×3

The next four rational numbers according to above pattern are,

−1×44×4,−1×54×5,−1×64×6,−1×74×7−416,−520,−624,−728

(iii)

Given, rational numbers are −16,2−12,3−18,4−24.

The pattern of the above rational numbers is,

−16=−1×16×1,2−12=1×2−6×2,3−18=3×1−6×3,4−24=4×1−6×4

The next four rational numbers according to above pattern are,

1×5−6×5,1×6−6×6,1×7−6×7,1×8−6×85−30,6−36,7−42,8−48
