450/3 = x.
150 = x.
So x = 150.
This means 45 is 30% of 150
0.036 is greater. 0.035 is less than 0.036.
To find (x-9)/3=2, we do
(x-9)/3=2
(x-9)/3×3=2×3
x-9=6
x-9+9=6+9
x=15
So, x is 15
Let
a= melon
b= servings of melon
c= slice of melon
equation 1
a= 6b
equation 2
a= cb
equation 3
2/3a=a-1/3a
2/3 = 6b-1/3a
2/3cb= 6b-1/3cb
6b= cb
c= 6 slices
There are 6 slices per serving, thus Stephen ate 6 slices over the weekend
