The first thing you should do to answer the question is to take each of the amounts to percentages:
 (1/4) * (100) = 25
 (1/4) * (100) = 25
 (5/12) * (100) = 41.67
 (1/12) * (100) = 8.33
 Adding all the amounts:
 25 + 25 + 41.67 + 8.33 = 100%

 Yes, they ate the equivalent of a whole bread
        
             
        
        
        
Any triangle where the sum of the angles is over or under 180 cannot exist. 
A 45-55-80 triangle can exist, but a 45-55-90 triangle cannot.
A 30-45-105 triangle can exist, but a 80-90-105 triangle cannot.
        
                    
             
        
        
        
I’m not sure where the question is here, but if it is a true or false, the pygmies do exchange with neighboring villages. They are hunters and gatherers, so rather than planting food, they gather. So this statement would be true
        
                    
             
        
        
        
Answer:
   (ab)/9
Step-by-step explanation:
The product of a and b is written ...
   ab
Division by 9 is indicated by a fraction with 9 in the denominator and the dividend in the numerator. In text form, it looks like ...
   (ab)/9
In typeset form it looks like ...
   
The parentheses are necessary in both cases if you want to make sure the product is formed before the division occurs. The Order of Operations requires that the contents of parentheses be evaluated first.
On the other hand, in text form, ab/9 is supposed to be evaluated left to right, so the multiplication should occur before the division. (There is no "left to right" for the typeset fraction in the case where there are no parentheses.)

<em>Comment on the question</em>
Technically speaking, There is no way to write the expression so that the multiplication is required before the division, because the associative and commutative properties of multiplication allow the sequence to be rearranged to any convenient order.
