An survey shows that 4 out of 7 families have two or more children. If 1421 families were surveyed, how many families had two or more children?

Respuesta :

812 families have two or more children.
To figure this out, we first divide 1421 by 7 to find 1 of 7 families. 1421/7=203. Then, we multiply 203 by 4, which gets us 812. 
Therefore, 812 families have two or more children.
Hope I helped! ;)
The answer is 812. 1421/7=203 and 203x4=812.
