1.1

1.

7/20 = 0.35

2.

1.(27) = (127 - 1)/(100 - 1) = 126/99 = 14/11

3.

1 7/8 = 1.875

4.

x² = 81 ⇒ x = √81 = ± 9

5.

x³ = 343 ⇒ x = ∛343 = 7

6.

x² = 1/100 ⇒ x = √1/100 = ± 1/10 = ± 0.1

7.

x² = 200 ⇒ x = √200 = 10√2 ≈ 14.14 ft

1.2

8.

121/√121 = √121 = ± 11 ⇒ Integer, Rational number, Real number

9.

π/2 ⇒ irrational number, Real number

10.

'All integers are rational numbers' ⇒ TRUE as each can be shown as p/q

1.3

11.

√8 + 3 < √9 + 3 = 3 + 3 = 6 ( < ) 8 + √3

12.

√5 + 11 > √4 + 11 = 2 + 11 = 13 ( > ) 5 + √11 < 5 + √16 = 5 + 4 = 9

13.

√99 ≈ 9.94, π² ≈ 9.869 , 9.(8) ≈ 9.888
π² < 9.(8) < √99

14.

√1/25 = 1/5 = 0.2, 1/4 = 0.25. 0.(2) = 0.222
√1/25 < 0.(2) < 1/4
