Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.
Step-by-step explanation:
Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.
4/9 is basically obtained when we multiply the denominator of 2/3 by 2 and denominator by 3, which is wrong.
Thus, the correction is as follows:
Given the fraction

Multiply the nominator and denominator of the fraction by 2

Thus, the 4/6 is the correct equivalent expression of 2/3.

Answer:
- 63 in the class
- (C+B)P' = 25
- (C+B+P)' = 18
Step-by-step explanation:
The number of students in the class is the total of all numbers on the diagram:
9 +5 +11 +6 +3 +4 +7 +18 = 63 . . . students in the 2015 senior class
__
Students taking Chem or Biology, but not Physics are those in the colored area, excluding those in the green:
9 +5 +11 = 25 science students not taking Physics
__
Students not taking science are those outside the colored areas:
18 students are not taking science
Answer:
x = 3/4
Step-by-step explanation:
Step 1: Find possibilities.
- We know one possibility: 8x - 6 = 0. This is because 0 cannot be positive or negative.
Step 2: Solve possibility 1.
(Add 6 to both sides)
(Divide both sides by 8)
Therefore, x = 3/4.
