What fraction of sixth-graders play sports?
The percentage is 35%, which can be written as 35/100.
Therefore, the fraction of sixth-graders who play sports is 35/100.
A 10/22
B 11/20
C 2/5
D 3/4
0.55 can also be written as 55/100, which can be simplified to 11/20.
Therefore, the fraction that represents the part of the candy bar that Daniel ate is option B, which is 11/20.
To convert a fraction to a percentage, we can divide the numerator by the denominator and then multiply the result by 100.
1 divided by 5 equals 0.2.
0.2 multiplied by 100 equals 20.
Therefore, 1/5 is equal to 20%.
So, 20% of the students in Jamie's class are boys.
Responses
A 3%, 0.3, 3/100
B 20%, 0.2, 2/10
C 40%, 0.4, 4/100
D 50%, 0.05, 5/10
3%, 0.3, 3/100
20%, 0.2, 2/10
Which value is equivalent to 3/10?
0.3
So, 0.3 is equivalent to 3/10.
What percentage is equivalent to the fraction of games the Falcons won?
To do this, we multiply the fraction 3/5 by 100.
3/5 * 100 = 60%
Therefore, the percentage equivalent to the fraction 3/5 is 60%.
-2 - (1/5)(10x + 15)
The coefficients in the given expression are 42, 56, and 7. To find their GCF, we find the largest number that divides evenly into all three numbers.
The GCF of 42, 56, and 7 is 7, as 7 is a common divisor of all three numbers.
Thus, Steven could factor the expression by dividing each term by 7.
Responses
A 7
B y
C z
D x
E 6
The expression contains x, y, and z.
To factor out a common factor, we need to find a factor that divides evenly into all terms of the expression.
Considering the variables, only x and y are common to all three terms.
Therefore, the possible common factors that Steven could use are:
D) x
B) y
Responses
A 1/4(x + 144)
B 1/4(x − 144)
C 1/4(x − 9)
D 4x − 9
By factoring out 1/4, we get: 1/4(x) - 1/4(36)
Simplifying further, we have: 1/4(x) - 9
Therefore, the equivalent expression is:
C) 1/4(x - 9)
A) 1/4(x + 144)
I appreciate your understanding.
A) 1/4(x + 144)
So the correct answer is A, not C.
