Question

Check whether the following quantities form a proportion or not:​(i) $3x,7x,24$ and $56$.

Answer 1

Find the ratio of first two and last two quantities:
Ratio of $3x\text{and}7x=\frac{3x}{7x}=\frac{3}{7}=3:7$

Ratio of $24\text{and}56=\frac{24}{56}=\frac{3}{7}=3:7$

Since, ratio of $3x\text{and}7x=$ ratio of $24\text{and}56$
Hence, the given quantities form a proportion .
