Studdy Solution

STEP 1

1. Nicolás practiced playing the cello for 2 hours and 18 minutes.
2. We need to convert the time spent practicing into a decimal format.

STEP 2

1. Convert minutes to hours.
2. Add the converted minutes to the total hours.
3. Express the total time as a decimal.

STEP 3

Convert the 18 minutes into hours. Since there are 60 minutes in an hour, divide 18 by 60.
Minutes in hours=1860 \text{Minutes in hours} = \frac{18}{60}

STEP 4

Calculate the decimal value of the minutes in hours.
1860=0.3 \frac{18}{60} = 0.3

STEP 5

Add the converted minutes to the total hours Nicolás practiced.
2+0.3=2.3 2 + 0.3 = 2.3

STEP 6

Express the total time Nicolás spent practicing as a decimal.
The time Nicolás spent practicing as a decimal is:
2.3 hours \boxed{2.3 \text{ hours}}
