How to turn a fraction into a percentage?
Brilliant_brown [7]
Convert the fraction<span> to a decimal number. The </span>fraction<span> bar between the top number (numerator) and the bottom number (denominator) means "divided by." So converting a </span>fraction <span>such as 1/4 to a decimal means you need to solve the math: 1 divided by 4.

i hope i helped

City A is 25% less than population of city B so city A's population is what % of city B
Lerok [7]

City A is 25% less than population of city B. So city A's population is 75% of city B

<h3><u>Solution:</u></h3>

Given that City A is 25% less than population of city B

To find: city A's population is what % of city B

From given information,

City A is 25% less than population of city B

A = B - 25% of B

So we can write as,

A = B - \frac{25}{100} \times B\\\\A = B - 0.25B\\\\A = 0.75B

A = 0.75B can be written as,

A = \frac{75}{100}\times B

city A = 75 % of City B

Thus city A's population is 75% of city B

\root(3)(-3)\root(3)(-5)=\root(3)(15) true or false
Oksi-84 [34.3K]

The equation \sqrt[3]{-3} \cdot \sqrt[3]{-5} = \sqrt[3]{15} is true

<h3>How to determine the true statement?</h3>

The equation is given as

\sqrt[3]{-3} \cdot \sqrt[3]{-5} = \sqrt[3]{15}

Apply the law of indices

\sqrt[3]{-3 * -5} = \sqrt[3]{15}

Evaluate the product

\sqrt[3]{15} = \sqrt[3]{15}

Both sides of the equation are the same

Hence, the equation \sqrt[3]{-3} \cdot \sqrt[3]{-5} = \sqrt[3]{15} is true
