Answer:
120
Step-by-step explanation:
So 10% <em>of</em> a number (let's use n) is 30.
The key word "of" tells us we need to multiply. Therefore, 10% times n is 30:
10% is the same as 0.1. So:
Divide both sides by 0.1:
So, our number is 300.
To find 40% of 300, multiply 0.4 and 300. Thus:
Our answer is 120.
And we're done!
