Area of a 25 inch TV screen is 300 in.² the area of a 40 inch TV screen is 768 in.² what area of the smaller screen is what percent of the area of the larger screen

So percent is parts out of 100

we want to find out 300/768 where the bottom number is 100

just divide it using a calulator and get 0.3906

that is 0.3906/1

make bottom number 100

multiply by 100/100

39.06/100

round to 39

39/100=39%

answer is 39%
