An advertisement says that 9 out of 10 dentists recommend sugarless gum. If the ad is true, how many of the 60 dentists in our city would recommend sugarless gum? Please help, bc I’m ready to choke to death on some gum

Hiya!

You can make a proportion


(9)/(10) = (x)/(60)

Cross multiply

60 × 9 = 540

540 ÷ 10 = 54

54 of the dentists would recommend sugarless gum
