Check whether the following quantities form a proportion or not?
3x, 7x, 24 and 56
3x, 7x, 24 and 56
✓
Answer
3x, 7x, 24 and 56
If these are in proportion, then
3x × 56 = 7x × 24
⇒ 168 x = 168 x
which is true.
Hence 3x, 7x, 24 and 56 are in proportion.
If these are in proportion, then
3x × 56 = 7x × 24
⇒ 168 x = 168 x
which is true.
Hence 3x, 7x, 24 and 56 are in proportion.
