the numerator of a certain fraction is four times the denominator. If 10 is added to both numerator and denominator the resultin
1 answer:
Okay so will have x be the denominator.
Numerator: 4x
Fraction:
which would be equivalent to 4.
If you add 10 to both the numerator and denominator the resulting fraction is
We multiply both sides of the equal side sign times (x + 10) we get...
4x + 10 = 2 * (x + 10)
4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5 < denominator
4x = 4 * 5 = 10 < So the fraction is 10/5

Answer:
She can make 9 uniform tops from the material left.
Step-by-step explanation:
Given:
Yards of material left on the bolt =
Material requirement for a uniform top for band members =
To find the number of tops that can be made from the material left.
Solution:
In order to find the number of tops that can be made from yards of material, we need to divide
by
.
Number of uniform tops that can be made is given as:
⇒
We first convert mixed number to fractions.
⇒
To divide fractions the fractions are multiplied after flipping the divisor.
⇒
⇒
⇒ 9
Thus, she can make 9 uniform tops from the material left.
