The local library has a children’s section with picture books and chapter books. The ratio is 2:3. If there are a total of 500 books in the children’s section, then how many chapter books are in the section?

there are 300 chapter books in the children's section

Step-by-step explanation:

the way you'd solve these kinds of problems is to turn it into an equation.

the ratio of 2:3 with a total of 500

becomes

2x + 3x = 500

2x + 3x = 500

combine like terms

5x = 500

divide both sides of the equation by 5

5x/5 = 500/5

x = 100

now, substitute x in the original equation.

2x + 3x = 500

200 + 300 = 500

There are 300 chapter books

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
