Step-by-step explanation:
Exponents are literally just a shorthand way of indicating a repeated multiplication of the same thing by itself. So Exponents are important in math because they will allow us to abbreviate something that would otherwise be really tedious to write or draw.
First change the 230 grams to kilograms or 1 kilogram to grams.
The units have to be the same.
Next set up a proportion.
Cross multiply to solve the proportion.
1 kg = 1000g
230 g/30 biscuits = 1000g/x biscuits
230x = 30(1000)
230x = 30000
divide both sides by 230
x =130 biscuits
