Answer:
120 is 30% of 400.
Step-by-step explanation:
Rate per 100 in simpler term is called a percentage.
Per-cent, as the word suggest, means every part out of 100.
So 30% will be equal to [tex]\frac{30}{100}[/tex].
Then assuming x to be the unknown number, we can write 30 percent of x equal to 120 as:
[tex]\frac{30}{100}[/tex] × [tex]x = 120[/tex]
[tex]x=\frac{120*100}{30}[/tex]
[tex]x=\frac{12000}{30}\\\\x=400[/tex]
Therefore, 120 is 30% of the number 400.
