We know that <span>Lola walks 4/10 mile to her friends house. then she walks 5/10 mile to the store. 
To solve the problem we have to use addition. 
4/10 + 5/10 = 9/10 
Lola walks 9/10 miles. </span>
        
                    
             
        
        
        
If he ate 4 of them, but it means he ate 2/5 muffins, 
4 muffins = 2/5 muffins
You substitute x muffins for how much muffins she baked in all -
2/5* x muffins = 4
2/5 multiply by 2/5 to cross it out. Do the same to the other side. 
x= 4 *5/2
x = 10 muffins
So there were 10 muffins in all
