Question

check whether the following numbers form a proportion or not. 1 1/3, 3 1/4, 4 1/2, and 9 3/4​
and answer it step by step​

Answer 1

Answer:

$1\frac{1}{3} ,$ $3\frac{1}{4},$ $4\frac{1}{2},$ $9\frac{3}{4}$ are NOT in proportion.

Step-by-step explanation:

Product of the Means $= 3\frac{1}{4} . 4\frac{1}{2}$

$= \frac{13}{4} . \frac{9}{2}$

$= \frac{117}{8}$

Product of the Extremes $=1\frac{1}{3} . 9\frac{3}{4}$

$=\frac{4}{3} . \frac{39}{4}$

$=13$

Therefore, Product of the Means ≠ Product of the Extremes

Therefore, $1\frac{1}{3} ,$ $3\frac{1}{4},$ $4\frac{1}{2},$ $9\frac{3}{4}$ are NOT in proportion.
