Question

Of the 125 people in a company , three-fifths have a smartphone . How many children do not have a smartphone

Answer 1

HAVE smart phones + do NOT have smart phones = 125

Have smart phones

`(3)/(5) *125 = (3(125))/(5) = 3(25) = 75`

HAVE + NOT = 125

75 + NOT = 125

-75 -75

NOT = 50

Answer: 50 people do not have a smart phone
