Evaluate ab for a = 2 3/4 and b = 4/5 a. 1 1/15 b. 8/15 c. 2 1/5 d. 2/3

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

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
