in a geography textbook,35% of the page is colored. if there are 98 colored pages, how many pages are there in the whole textbook?

There are totally 280 pages in that book

Step-by-step explanation:

let the total pages be x.

From the question we know that 98 pages are the 35% of total pages...

so,

(98/x)*100 = 35

98/x = 35/100

reciprocal both sides...

x/98 = 100/35

x = 2.857 * 98

x = 280

if the rectangular pool has a area of 192 square ft. and length of 15 ft. you must divide 15 into 192. 192 ÷ 15 = about 13 ft.

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2
