Question

find the ratio 20 min to 160 sec​

Answer 1

Answer:

7.5 second

Step-by-step explanation:

1 min = 60 second

So,

20 min = 60×20

= 1200

Now,

1200/ 160 = 7.5 second

Calculation

Just cut the zero's from 1200/60 .So it would be 120/6 and just simply divide and the answer would be 7.5 .

Answer 2

Answer:  7.5 or 15 : 2

Now let's see how we get that answer

first we convert everything to seconds since that is the smallest unit in the question, so we know that

1min = 60 sec so

20min = 60 x 20

20min = 1200sec

so now we have

1200 : 160

and this can be written as 1200/160 now we can cancel one of the zeroes off from the numerator and denominator since it's common so it would become

120/16

now 120 and 16 is a multiple of 8 so we can simplify it again by dividing the numerator and denominator by 9, so

15/2 we can simplify it any further since 15 is a prime number so now we can put it back in the form of ratio

15 : 2

if you want it in the form of decimal then we can divide 15 by 2 to get

7.5
