Answer:
27 pizzas
Step-by-step explanation:
Each brick of cheese can make 3 pizzas since there are 3 thirds in 1. We multiply 3 by the total number of bricks to get 27.
 
        
             
        
        
        
First, we must find the common denominator (12)            ✵
10/12-6/12            ✵                 ✵                              ✵                              ✵
Now, why 10?                                     ✵                   ✵                      ✵
Because we CAN'T just take the denominator and change it; we must change both the denominator AND the numerator:
✵                                      •          -                                      ○          
4/12                  ✧                             ✩                                  ✶            ✺         ✱   
We can simplify, or reduce, this fraction:                  ✱  ✱
1/3              ✩                              ✦                                        ✤ 
I hope it helps!

 
        
                    
             
        
        
        
Answer:
b = 3/4
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
3/ 40 = 1/2 b ( 1/5)
Multiply
3/40 = 1/10 b
Multiply each side by 10
10 *3/40 = 10* 1/10 b
3/4 = b
