Answer:
There will be 330 7th grade students in this middle school this year.
Step-by-step explanation:
Last year enrollment = 150 students
As the enrollment increased by 120%.
i.e.
Number of Percentage increase = 120% × 150 = 120/100 × 150
= 1.2 × 150
= 180
Thus,
Total students this year = No. of Percentage increase + Last year students
= 180+150
= 330 students
Therefore, there will be 330 7th grade students in this middle school this year.
We can solve this problem by dividing 9/12 by 2/12. We should do this because to find how many sets of something are in a number, the question is asking us to do division. Doing this, we get 9/12 * 12/2, giving us our answer of 4.5 sets of 2/12 in 9/12.
A proper fraction is a fraction such as 3/5, or 2/4, any fraction where the numerator is less than the denominator. Then it says "the whole is divided into an even number of equal parts, and an odd number of those parts exists." Such as 1 3/5. From my understanding, you then divide by 2, which would give you 0.8, which could then be turned into 0.4 if that's what your teacher wants you to do. In the end, there will be no odd number.
Let the number be x
reciprocal=1/x
2 more the reciprocal=1/2+x
but 1/2+x=3(1/x)
1/2+x=3/x
x=6+3x
x=-2
