Pls Do it in th steps​

Answer 1

Answer:

Step-by-step explanation:

If 1 : 15 and 3 : 45 are in proportion, then we can write it as,

1 : 15 :: 3 : 45

We know that,

Product of means = Product of extremes

Product of means = 15 × 3 = 45

Product of extremes = 45 × 1 = 45

Hence, 45 = 45

and

Product of means = Product of extremes

∴ 1 : 15 and 3 : 45 are in proportion.
