When multiplying by a power of 10 (10, 100, 1000, etc.) we can just move the decimal of the other number to the right. Since were multiplying by 1000, we move the decimal to the right 3 times. The answer is 32,180.
D=dollars earned
T=time spent painting the fence.
(1,5) (2,10) (3,15)
D=5T
The solution is the set of numbers that can be written in place of
all the variables and make all of the equations true.
If you're asking for the actual numbers, there's nobody in the world
who could find those without seeing the system of equations.
Set up a proportion. 4 3/4 cup broth is to 10 servings as x cups broth is to 1 serving soup.
x= amount of broth in one serving
(4 3/4)/10= x/1
cross multiply
(4 3/4)(1)= 10x
convert 4 3/4 to improper fraction
(19/4)(1)= 10x
19/4= 10x
divide both sides by 10
19/4 ÷ 10= x
to divide fractions, multiply by reciprocal of 10
19/4 * 1/10= x
multiply numerators; multiply denominators
(19*1)/(4*10)= x
19/40 cup= x
ANSWER: 19/40 cup in one serving
Hope this helps! :)
