Question

State 10: 30: : 15: 45 is in proportion or not.

Answer 1

Step-by-step explanation:

For the numbers to be in proportion

Product of middle terms = Product of extreme terms

So,

product of middle terms = 30*15= 450

product of extreme terms = 45*10= 450

thus, 10: 30: : 15: 45 are in proportion
