Answer 2

1. a) To solve the expression 4/5 × 5, you can simplify it as follows:

4/5 × 5 = (4 × 5) / 5 = 20 / 5 = 4

Therefore, the value of a) is 4.

2. b) To solve the expression 2/9 ÷ 5/6, you can divide the numerator of the first fraction by the denominator of the second fraction and multiply it by the reciprocal of the second fraction:

(2/9) ÷ (5/6) = (2/9) × (6/5) = (2 × 6) / (9 × 5) = 12 / 45

To simplify this fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 3:

12 / 45 = (12 ÷ 3) / (45 ÷ 3) = 4 / 15

Therefore, the value of b) is 4/15.

3. c) To solve the expression 6/7 × 7, you can multiply the numerators and denominators:

(6/7) × 7 = (6 × 7) / 7 = 42 / 7 = 6

Therefore, the value of c) is 6.

4. g) To solve the expression 5/8 ÷ 15, you can divide the numerator by the denominator:

(5/8) ÷ 15 = (5/8) / 15 = (5/8) × (1/15) = 5 / (8 × 15) = 5 / 120

To simplify this fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 5:

5 / 120 = (5 ÷ 5) / (120 ÷ 5) = 1 / 24

Therefore, the value of g) is 1/24.
