Question

check whether the number
10, 12, 15, 18 are in proportion or
not​

Answer 1

Answer:

Yes they are in proportion.

Step-by-step explanation:

Proportion => Product of extremes = Product of means

10×18 = 12×15

=> 180 = 180

∴ L▪︎H▪︎S = R▪︎H▪︎S

So, the numbers are in proportion.

Answer 2

Answer:

Yes, these are in proportion.

Explanation:

Proportion is an equation that defines that the two given ratios are equivalent to each other.

Solution:

Given numbers are 10,12,15,18.

If a, b, c, d are in proportion i,e $a:b::c:d$

Then product of extremes = product of means ($a.d=b.c$)

$10:12::15:18$

$a:b::c:d$

$10\times18=12\times15\\180=180$

If the product of extremes is equal to the product of means , then the given numbers are in proportion.

So, $10,12,15, and 18$ are in proportion
