a hill has a foot but no legs

?

?

a mountain is tall when it is young and short when it is old

mary is the fifth daughters name

the pocket still has air in it

there are no stairs in a one-story house

the son has two dads

write as 21/8 * 11/4

mulptiply 21/8 by 125 to get 2625/1000

multiply 11/4 by 250 to get   2750/1000

2625/1000 becomes 2.625

2750/1000 becomes 2.75

multiply to get 2.625*2.75=7.21875

(i know there is an easier way but i cant think of it off the top of my head)

2+5-56778654+485849*393847756-33747930(687)+568475667/3=

2+5-56778654+191350538404844-23184827910+189491889=191327486290176

6567565+5756433=12323998

the equation is na+nb+nc+nd+ne=1500

where a=5 b=10 c=20 d=50 and e=100

remove the lowest common denominator of 5 to get

na+nb+nc+nd+ne=300

where a=1 b=2 c=4 d=10 and e =20

a is now irrelivent as n*a=n so

n+n(2)+n(4)+n(10)+n(20)=300

37n=300

n=300/37

n=8.108108 repeating

length X width X height

write as improper fraction 13/10 + 1/4

                                          *2          *5

                                         26/20 + 5/20= 31/20

12.75 is 25% or 1/4 of a number so 12.75*4 is 51
