The multiplicative inverse of 3 1/5 is

The multiplicative inverse of 3 1/5 is5/31 .

Step-by-step explanation:

please mark me brainliest

3 1/5 = 16/5 (If 3 1/5 is a mixed number)

=> The multiplicative inverse of 3 1/5 is 5/16

Step-by-step explanation:

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
