  A number written in scientific notation follows the following pattern:
 m * 10 ^ e

 The number m is called "mantissa" and e the "order of magnitude"
 For this case we have:
 0.000007

Can someone help. Write a word problem about equal groups and act it out to solve
Alona [7]

Answer:

HOPE THAT MAY HELP YOU :)

Step-by-step explanation:

Equal groups are illustrations of using the same variable.

A word problem that uses equal group is:  

Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled  

The only condition for equal groups is that:  

The units or variable must be the same  

For instance:

Add 5 miles and 4 miles ----- This represents distance

Remove 2 liters from 7 liters --- This represents volume

Add 5 hours and quarter of an hour -- This represents time

And so on.
