Question

Determine whether the given numbers are in proportion 32, 48, 80, 150

Answer 1

a÷b= b÷c = c÷d
32÷48=48÷80 =80÷150
2÷3=3÷5=8÷15
therefore , it is not in proportion

Answer 2

Answer :

No, the numbers are not in proportion.

Step-by-step explanation :

A group of numbers is said to be in proportion if the product of their extremes is equal to product of their means.

Here,

32, 48, 80, 150

Extremes = 32 and 150

Product if extremes = 32 * 150 = 4800

Means = 48 and 80

Product of means = 48 * 80 = 3840

So, we conclude that ;

4800 ≠ 3840

∴ Product of extremes ≠ Product of means.

Hence, the given set of numbers are not in proportion.
