Answer is probably Number 1.
The fraction is defined as a number in the form of a/b where a nd b are integers and b is not equal to zero. Sarah has left with 120 balloons.
A fraction is used to represent a portion or part of anything. It consists of two parts a numerator and a denominator. For example 1/4 is a fraction where numerator is 1 and denominator is 4.
The total number of packages = 8
Number of balloons in each package = 20.
The portion of balloons use to decorate hall = 1/4.
Suppose the remaining balloons are x.
Thus the expression for remaining balloons can be written as,
x = 20 × 8 - 1/4×(20 × 8)
x = 160 - 40
= 120.
Hence, Sarah has left with 120 balloons and the expression for left balloons is x = 20 × 8 - 1/4×(20 × 8).

Answer:
(8 × 20) ÷ 4
40
Step-by-step explanation:
8 × 20 = 160
160/4 = 40
Answer:
width=25/3
Length=75/3
Step-by-step explanation:
Given
Perimeter=50
Let width=x
Length=4x
So perimeter =2(length+width)
2(length+width)=50
2(X+2x)=50
3x=25
X=25/3
So width=25/3
Length=75/3
12 students
40% earned a B; 20% earned an A, so (40%+20% =) 60% got a "B or better."
60% of 20 students is ...
... 60/100 × 20 students = 1200/100 students = 12 students
Answer:
70°
Step-by-step explanation:
61° + 49° + y = 180° (sum of angles of a triangle is always 180°)
so,
y= 180° - 61° - 49° = 70°

Answer:
1/16
Step-by-step explanation:
To have one real solution, the discriminant must be 0.
b² − 4ac = 0
1² − 4a(4) = 0
1 − 16a = 0
a = 1/16
