finding the worth of the unit fraction will help you to solve each problem below.
1. if 4/5 of a number is 16, what is 1/5 of the number?
4/5 * x= 16
divide both sides by 4
1/5 x = 4
One fifth of the number is ...four.
To find the value of 1/5 of a number, you can follow these steps:
1. Set up an equation using the given information. In this case, you know that 4/5 of a number is equal to 16. So, the equation is 4/5 * x = 16, where x represents the unknown number.
2. Simplify the equation. Multiply both sides of the equation by the reciprocal of 4/5, which is 5/4. This will eliminate the fraction on the left side of the equation. The equation becomes (4/5 * x) * (5/4) = 16 * (5/4).
3. Simplify further. The 4 in the numerator and the denominator on the left side of the equation cancel out, leaving you with x = 16 * (5/4).
4. Calculate the result. Multiply 16 by 5/4 to get the value of x. 16 * (5/4) equals 20.
Therefore, 1/5 of the number is 4.
