Two rock samples have masses of56.24 grams and 8.98 what is the estimated total mass if round the decimals to the nearest tenth 

To estimate the total mass of the two rock samples, we'll round each mass to the nearest tenth and then sum them.

1. \( 56.24 \) grams rounds to \( 56.2 \) grams (since 4 is less than 5, we round down).
2. \( 8.98 \) grams rounds to \( 9.0 \) grams (since 8 is greater than 5, we round up).

Now, adding these two rounded masses:

\[
56.2 + 9.0 = 65.2 \, \text{grams}
\]

The estimated total mass is **65.2 grams**.
