Question
Determine if the following numbers are in proportion: $4, 6, 8, 12$
✓
Answer
$4, 6, 8, 12$ If it is in proportion,
then If $ad = bc if 4 \times 12 = 6 \times 8$ If $48 = 48$ Which is true
$\therefore$ $4, 6, 8, 12$ are in proportion
then If $ad = bc if 4 \times 12 = 6 \times 8$ If $48 = 48$ Which is true
$\therefore$ $4, 6, 8, 12$ are in proportion
