To convert a fraction to a percent, simply divide the numerator by the denominator and multiply the quotient (the result) by 100.
1.

Divide 13 by 50 to receive the quotient
13÷50=0.26
Multiply the quotient by 100 or simply move the decimal two places to the right.
0.26×100=26
Add the "percent" symbol to your answer. (%)
As a result, the percent form of

is 26%
Similarly, all the fractions will follow the same procedure, in order for them to be converted to a percent. Simply add the percent symbol (%) after the result.

Percent means "out of 100" or "parts per 100". For cases where the numerator is larger than the denominator (improper fraction), such as 7/5, the result will be larger than 100% as well, as the total number of parts exceeds the parts available.
Answer:
7,854 cm squared
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr^2
Filling in the given radius gives you ...
A = π(50 cm)^2 = 2500π cm^2 ≈ 7854 cm^2
Answer:
The prices decreased from $245,000 to $215,000. This is about a (I don't know this one)
Answer:
A rational number is said to be closed if the subtracted values and the result obtained are rational. Hence, the equations which supports the condition are :
5.5 - 0.5 = 4
5√4 - √4 = 4√4
Step-by-step explanation:
A.)
√8 - √8 = 0 ; the added values aren't rational and the result, Zero is not rational either.
B.)
5√4 - √4 = 4√4
5(2) - 2 = 2(2)
10 - 2 = 4
All the values in the expression are rational ; hence, it supports the assertion.
C)
5.5 - 0.5 = 4 ; all the values in the expression are rational, hence, it supports the fact.
2√3 - √3 = √3 ; the values in the expression are not rational, hence, it does not meet the condition.
Therefore, only options B and C supports the assertion.
Let me add that I learned most of this from Brainly a user named fichoh :)
21.12 is 25.6% of 82.5. I hope this helps. :)
