Which ratio is equal to 15:20?

Mathematics
1 answer:
Basile [38]2 years ago
4 0

Answer:

21 to 28

Step-by-step explanation:

Reduce each ratio to lowest terms by dividing by any common factors. (It helps to know your multiplication tables, or a quick way to find the greatest common divisor.)

15 : 20 = (5*3) : (5*4) = 3 : 4

_____

21 : 28 = (7*3) : (7*4) = 3 : 4 . . . . same as 15 : 20

5 : 10 = (5*1) : (5*2) = 1 : 2 . . . . . ≠ 3:4

18 : 25 . . . has no common factors . . . ≠ 3:4

Can Somebody Please Explain How To Do It? THANKS
sergejj [24]

Hello from MrBillDoesMath!

Answer:

9


Discussion:

Solution 1:

Distance between two points (x1, y1), (x2,y2) is given by the formula

sqrt(  (x1-x2)^2 + (y1-y2)^2).  In our case this becomes

sqrt( (0-0)^2 +  (12 -3)^2 ) =

sqrt( 9^2) =

9.


Solution 2:

Note points D and E both have x = 0 so segment DE is a vertical segment. The length is simply the difference of the y coordinates: 12- 3 = 9 as before.


Thank you,

MrB
