Question

two percent of jennie's skin cells were burned when she escaped the fire. If 3.7 x 10 to the tenth of her skin cells were burned , how many cells were not burned

Answer 1

Number of unburnt cells, x= 151.9 x 10^10

Explanation:

Number of unburnt cells= x

x = ?

Given: 2% cells are burnt

(3.1 x 10^10 cells)/2% = x/98%

x = (3.1 x 10^10)(98%/2%)

=(31000000000)(49)

x =151.9 x 10^10
