Answer:
The full mass is 500 kg.
Step-by-step explanation:
Let's break this down.
4% of the mass is 20 kg.
4% = 4/100 or 0.04
"of" = multiply
mass = our unknown value, x
is = equal sign
20 kg = our end result
Let's make an equation out of this.
4% of the mass is 20 kg.
0.04 • x = 20
Divide both sides by 0.04.
x = 500
The full mass is 500 kg.
