Agroup of friends went on a holiday to a hill station. it rained for 15 days. but when it rained in the morning, the afternoon was lovely. and when it rained in the afternoon, the day was preceded by clear morning. altogether there were 12 very nice mornings and 13 very nice afternoons. how many days did their holiday last?

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
