Answer:
Explanation:
1. 36% of x is 216 find x.
36/100 × X = 216
36x/100 = 216
36x = 216×100
36x = 21600
x = 21600/36
x = 600
2. 125% of a is $1 find a.
125/100 × a = $1
125a = $100
a = $100/125
a = $4/5 = $ 0.8
3. 5% of 500 g is x. Find x
X = 5/100 × 500g
X = 5 × 5g = 25g
4. 0.25% of $1 is x. Find x
X = 0.25/100 × $1
X = $0.25/100
X = $0.0025
