At the end of a soccer game, the head coach noticed that the jug of water, which had initially contained 8 9/10 gallons, was down to 1 7/10 gallons. How many gallons of water had been consumed? Write your answer as a fraction or as a whole or mixed number. _____ gallons

Identify amounts of water: Step 1: Identify the initial and remaining amounts of water. Initial amount: 8 9/10 gallons, Remaining amount: 1 7/10 gallons. We need to subtract the remaining amount from the initial amount to find out how much water was consumed. Calculation: 8 9/10 - 1 7/10Convert to improper fractions: Step 2: Convert mixed numbers to improper fractions for easy subtraction. 8 9/10 = (8×10 + 9)/10 = 89/10, 1 7/10 = (1×10 + 7)/10 = 17/10. Now subtract: 89/10 - 17/10Perform subtraction: Step 3: Perform the subtraction. 89/10 - 17/10 = (89 - 17)/10 = 72/10 = 7 2/10 or 7.2 gallons. This is the amount of water consumed.

Identify amounts of water: Step $1$ : Identify the initial and remaining amounts of water. $\newline$ Initial amount: $8\frac{9}{10}$ gallons, $\newline$ Remaining amount: $1\frac{7}{10}$ gallons. $\newline$ We need to subtract the remaining amount from the initial amount to find out how much water was consumed. $\newline$ Calculation: $8\frac{9}{10} - 1\frac{7}{10}$
Convert to improper fractions: Step $2$ : Convert mixed numbers to improper fractions for easy subtraction. $\newline$ $8 \frac{9}{10} = (8\times10 + 9)/10 = \frac{89}{10}$ , $\newline$ $1 \frac{7}{10} = (1\times10 + 7)/10 = \frac{17}{10}$ . $\newline$ Now subtract: $\frac{89}{10} - \frac{17}{10}$
Perform subtraction: Step $3$ : Perform the subtraction. $\newline$ $\frac{89}{10} - \frac{17}{10} = \frac{89 - 17}{10} = \frac{72}{10} = 7 \frac{2}{10}$ or $7.2$ gallons. $\newline$ This is the amount of water consumed.
