- Question: Ratio of 1 kg to 500 g is ___ antecedent is ___ consequent is ___
- Answer:
- Ratio: [tex]\( 1000:500 \)[/tex]
- Antecedent: 1000 (since [tex]\(1 \text{ kg} = 1000 \text{ g}\)[/tex])
- Consequent: 500

1.J c)
- Question: The compounded ratio of [tex]\( p : q \)[/tex] and [tex]\( r : s \)[/tex] is ___

- Answer: The compounded ratio is [tex]\( 0.75 \)[/tex]

1.J e)
- Question: If [tex]\( \frac{a}{b} = \frac{1}{2} \)[/tex] and [tex]\( \frac{b}{c} = \frac{2}{3} \)[/tex], then [tex]\( \frac{a}{c} = \)[/tex] ___
- Answer: [tex]\( \frac{a}{c} = 0.3333333333333333 \)[/tex] (which is [tex]\(\frac{1}{3}\)[/tex])

1.J f)
- Question: If [tex]\( x : y = 1 : 2 \)[/tex] and [tex]\( y : z = 4 : 3 \)[/tex], then [tex]\( x : z = \)[/tex] ___
- Answer: [tex]\( x : z = 0.6666666666666666 \)[/tex] (which is [tex]\(\frac{2}{3}\)[/tex])
