at one scholl at prep level there were 5 set of twins,two sets of triplets and one set of quadruplets starting school this year.
katen-ka-za [31]

Answer:  Fraction of twins = \frac{5}{8} Fractions of triplets = \frac{1}{4} Fractions of quadruplets = \frac{1}{8}

Step-by-step explanation:

Since we have given that

Number of set of twins = 5

Number of sets of triplets = 2

Number of sets of quadruplets = 1

Total number of sets is given by

5+2+1=8

Now, we need to find the fraction of those students.

So, Fraction of twins is given by

\frac{5}{8}

Fractions of triplets is given by

\frac{2}{8}=\frac{1}{4}

Fractions of quadruplets is given by

\frac{1}{8}
