What is the ratio of quarters to nickels in a dollar
sleet_krkn [62]

For quarters we have:

0.25x = 1

Where,

x: number of quarters

Clearing x we have:

x = \frac{1}{0.25}\\x = 4


For nickels we have:

0.05y = 1

Where,

y: number of nickels

Clearing y we have:

y = \frac{1}{0.05}\\y = 20


Then, the ratio of quarters to nickels is:

\frac{x}{y}= \frac{4}{20}

Simplifying we have:

\frac{x}{y} = \frac{1}{5}


Answer:

The ratio of quarters to nickels in a dollar is:

\frac{x}{y}= \frac{1}{5}

jarptica [38.1K]
First, you set up the equation which would be 5y-8=3y-4.
                                                                             -3y       -3y
                                                                               2y-8= -4
                                                                                 +8    +8
                                                                                  2y=4
                                                                               divide by 2    
                                                                                   y=2

If 1/10m = 1/11m + 1/1100, what is the value of m?
valentinak56 [21]
\frac{1}{10m} =  \frac{1}{11m} +  \frac{1}{1100} &#10;
\frac{1}{10m} =  \frac{1*1100 + 1*11m}{11m*1100}
\frac{1}{10m} =  \frac{1100 + 11m}{12100m}
1*12100m = 10m(1100 + 11m)
12100m = 11000m + 110 m^{2}
12100m-11000m = 110 m^{2}
1100m = 110 m^{2}
m=10
