She then takes a shortcut across the field, which is 1/4 mile long.

Answer: Ricki's route to school is 19/20 miles long.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

  • Sidewalk: 7/10 miles
  • Shortcut: 1/4 miles

So, to calculate the length of Ricki's route to school we have to simply add both lengths. (Sidewalk and shortcut)

Mathematically speaking:

7/10 + 1/4 = 14/20+ 5/20 = 19/20 miles

Ricki's route to school is 19/20 miles long.

Answer: The length of Ricki's route to school is [tex]\frac{19}{20} mile[/tex]

Step-by-step explanation:

  If Ricki walks 7/10 mile initially and later walked 1/4 mile, we can calculate the length of Ricki's route to school from her home by simply adding the fractions before us. If we do this properly, we will know exactly how long her  route is from her home.

 That is: [tex]\frac{7}{10} + \frac{1}{4}[/tex]

We will find the lowest common multiple of the two denominators of the fraction (10 and 4) and make the result the common denominator and then combine the fractions:-

 The l.c.m is 20. This will now be the common denominator. Now, use 10 (the denominator of 7/10) to divide the l.c.m(20) and multiply the result by the numerator (7); Then put the "+" sign. Repeat this process for the other fraction (1/4) and then add the new numerators. If you do this properly, you would have the fraction below:

         [tex]\frac{14 + 5}{20} = \frac{19}{20}[/tex]

Therefore, the length of Ricki's route to school is 19/20 mile
