(D) 16:17​

Answer 1

Answer:

b.4.3

Step-by-step explanation:

15×m=20×n

15m=20n

m/n=20/15

=4/3

=4:3 answer

Answer 2

the ratio of m:n is 4:3.

the correct option is (B).

Given:

m X 15% = n x 20%

To find:

the ratio of m:n

Solution:

• the ratio is the relation between the two same units which shows how much bigger the quantity is than the other.
• representation of two quantities says 'm' and 'n' is m:n which is read as ' m is to n'.

from the given,

m x 15% = n x 20%

⇒m x 15/100 = n x 20/100

⇒m/n = 20/100 x 100/15

⇒m/n = 20/15

⇒m/n = 4/3

⇒m:n = 4:3

so, the ratio of m:n = 4:3.
