Can you please help me with this question? What is 4% of 350?
OlgaM077 [116]
X = 4% * 350

x = 4/100 * 350

x = 4/10 * 35

x = 0.4 * 35

x = 14


14 is 4 percent of 350.
___________________

\sf\ .04=\frac{4}{100}\\\\x=\frac{4}{100}\times350\\\\x=\frac{4\times350}{100}\\\\x=\frac{1400}{100}={\boxed{14}
