Question

Determine the following are in proportion:

$44,121,16,44$

Answer 1

Checking whether the numbers are in proportion or not

Four numbers $a,b,c,d$ are said to be in proportion if $a:b$ and $c:d$ are equivalent ratios.

Now, converting the numbers into ratios

$44:121\mathrm{and}16:44$

$\frac{44}{121}$ and $\frac{16}{44}$.

Converting the following in the lowest form:

$\frac{4}{11}$and $\frac{4}{11}$.

Since, both the ratios are equivalent ratios.

Hence, $44,121,16,44$ are in proportion.
