Answer:
52 students
Step-by-step explanation:
From the question above, we have the following information:
a) Vidya ranks 7th from the top.
Mathematically,
Vidya = 7th student
b) Divya 3 ranks behind Vidya.
Divya = Vidya + 3
Hence, Mathematically:
Divya = 7 + 3 = 10
Divya = 10th student
c) Also, Divya is 7 ranks ahead of Medha.
Mathematically,
Medha = 10 + 7= 17
Medha= 17th student
d)Sushma is 32 ranks behind Medha
Mathematically,
Sushma = Medha + 32
= 17 + 32 = 49
Sushma is the 49th student
Therefore, since, Sushma is 4th from the bottom, total number of students is:
49 + 3 = 52 students
Answer:
8.413 x 10^3
Step-by-step explanation:
Answer:
3/6 + 3/12 = 49

Step-by-step explanation:
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(6, 12) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 12 = 72. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - twenty-three sixths plus three twelfths = forty-nine twelfths.
Will got 12 and John got 24.
You would set the equation as:
36=n+2n
Combine like terms
36=3n
Divide 3 from both sides
12=n
If you want to check it
12+2(12)=36
12+24=36
36=36
