Question

if m isdirectly proportional to n when m is3 and n is12 find the value of when n is 28​

Answer 1

Answer: 7

Step-by-step explanation:

when m = 3

n = 12

or m:n = 3:12

dividing both by 3 , we get

m:n = 1:4 (when m is 1 , n is 4 ) which is the same as our initial proporion.

when n = 28 , we have to find the value of m,

to get m from n, we have to divide with 4 ,

(since m =1 and n =4, if we divide n/4 =4/4 = 1 = m ,

so if we divide n with 4 we will get the corresponding

value of m )

since n=28 , we divide with 4

28/4 = 7 = m

therefore the value of m is 7 when n is 28

Answer 2

Answer:

answer is 7

Step-by-step explanation:

given that

m directly proportional to n

means if m value increase n value also increase

so when value of m is 3

• n value is 4 times of m means 12

• now if value is 28 of n

• then m 4 times less of n

means 28 /4

• answer comes 7
