2.2188
3.15208
4.72086

Respuesta :

Answer:

It is obviously d. 72086 as it becomes 72096 when the digit is replaced.

This is something you will quickly come to recognise easily however the way to work out what is the biggest change is
1.9470 - 1.8470 = 0.1
2.2199 - 2.2188 = 0.0011
3.15209 - 3.15208 = 0.00001
4.72096 - 4.72086 = 0.0001
Therefore the first one is the biggest change
