Answer:
56 : 28 as 122 : 61
Explanation:
Proportion says that two ratios or fractions are equal.
As per the statement:
56 : 28 :: 122 : ?
Let x be the fourth proportion.
then;
56 : 28 :: 122 : x
by definition of proportion:
![(56)/(28)=(122)/(x)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/hov632knyum0hes3uiviofs89rj7oyo94k.png)
by cross multiply we have;
![56x = 3,416](https://img.qammunity.org/2019/formulas/mathematics/middle-school/kv8acwnslmjjdj0ffjgg05xath99ix8r6f.png)
Divide both sides by 56 we have;
x = 61
Therefore, 56 : 28 as 122 : 61
