Suppose that seven in ten couples disagree on a particular matter. what percent of couples disagree on the matter?

The percent of couples disagree on the matter=70%

Step-by-step explanation:

We have given that seven in ten couples disagree on a particular matter.

Thus, the ratio of couples disagree to the total couples=

To convert it in percent we need to multiply it with 100, we get

The percent of couples disagree on the matter

⇒The percent of couples disagree on the matter=70%

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
