Answer: Well, each grandparent would only have two parents, and those parents would each have two parents, unless adoption was involved, so there would be four grandparents for each grandparent. Eight would be your answer, I think.
The required, 17 heartbeats in 15 seconds and 68 heartbeats in 60 seconds are equivalent.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
17 heartbeats in 15 seconds
Ratio = 17 / 15
Now,
68 heartbeats in 60 seconds
Ratio = 68 / 60
= 17 × 4 / 15 × 4
= 17 / 15
Thus, the required, 17 heartbeats in 15 seconds and 68 heartbeats in 60 seconds are equivalent.
