Sergio walked to and from school on 3/5 of the days in one month. He got a ride to school on 7/8 of the remaining days. On the one remaining school day that month he stayed home with a cold. How many school days were there that month?

there were 20 school days that month

Step-by-step explanation:

Let x represent the number of school days that were there that month.

Sergio walked to and from school on 3/5 of the days in one month. This means that the number of days that he walked to and from school is 3x/5

The remaining number of days would be

x - 3x/5 = 2x/5

He got a ride to school on 7/8 of the remaining days. This means that the number of days in which he got a ride to school is

7/8 × 2x/5 = 7x/20

The remaining number of days would be

2x/5 - 7x/20 = (8x - 7x)/20 = x/20

On the one remaining school day that month he stayed home with a cold. This means that

x/20 = 1

x = 20 × 1 = 20

i'm sure goog can you get that answer

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
