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.

IrinaK [193]

Answer: The fraction of set of twins= $\frac{5}{8}$

The fraction of sets of triplets= $\frac{2}{8}$

The fraction of set of quadruplets= $\frac{1}{8}$

Step-by-step explanation:

Given: The number of set of twins=5

The number sets of triplets = 2

The number of set of quadruplets=1

⇒ The total number of multiple birth students =5+2+1=8

∴ The fraction of set of twins= $\frac{\text{set of twins}}{\text{ total multiple birth students}}=\frac{5}{8}$

∴ The fraction of sets of triplets= $\frac{\text{set of triplets}}{\text{ total multiple birth students}}=\frac{2}{8}$

∴ The fraction of set of quadruplets= $\frac{\text{set of quadruplets}}{\text{ total multiple birth students}}=\frac{1}{8}$
