Problem: the first , second and third terms of the proportion are 56 , 16 , 49 . find the fourth term .
Rationale: explanation : let the fourth term be x . thus 56 , 16 , 49 , x are in proportion . product of extreme terms = 56 x product of mean terms = 16 x 49 since , the numbers make up a proportion therefore , 56 x = 16 49 or , x = ( 16 49 ) / 56 or , x = 14 therefore , the fourth term of the proportion is 14 . answer : b
annotated_formula: divide(multiply(49, 16), 56)
