round 78.97 to the nearest tenth.

Explanation:

Step1: Identify the tenths digit

In $78.97$, the tenths digit is $9$, and the digit to its right (hundredths place) is $7$.

Step2: Apply rounding rule

Since the hundredths digit ($7$) is $\geq5$, add $1$ to the tenths digit: $9 + 1 = 10$. Carry over the $1$ to the ones place: $8 + 1 = 9$, and set the tenths place to $0$.

Answer:

$79.0$
