Answer:
1)A ratio is a comparison between two or more like quantities in the same units.
Example:
a)The ratio of boys to girls is 2:3 or 2/3
b)The ratio of girls to boys is 3:2 or 3/2
2)In simple terms, the unitary method is used to find the value of a single unit from a given multiple and vice versa.
3)two equivalent ratios of 3 is to 7 hour
9:21 and 15:35.
4)the simplest form of 16 :4 is 4:1
5) the fractional form of 5 : 2 is 5 / 2.
6)The ratio of 45cm and 5m is:
first p must convert 45cm to metres.
45cm = 45/100m
45/100/5= 9m/100m = 9m:100m
7) first we have to convert kg to grams
1kg = 1000 grams
so 1/2kg = 500 grams
225/500 = 45/100 = 9/20 = 9g:20g
8) first we have to convert days to hours to get the ratio.
one day is 24 hours
so2 days = 24 ×2= 48 hours
Now, 48 hours/10 hours = 24/5 = 24 : 5
9) cost of 5 books is 180
therefore cost of 1 book = 180 / 5 = Rs.36
cost of such 14 books = 36 × 14 = Rs.504
10)
given: cost of 16 pencils = 96
therefore cost of one pencil = 96/16
rest of the question is not clear.
Hope it helps ☺️
