Question

please answer this what i shoul write it

Answer 1

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 ☺️
