Answer:
890 or 89 tens
Explanation:
Tens is numerically converted into 10
This means that:
79 tens = 79 * 10 = 790
10 tens = 10 * 10 = 100
Now, we can simply add the two numbers:
790 + 100 = 890
If we want to write in as "tens", we will simply remove 10 as follows:
890 = [tex] \frac{890}{10} [/tex] = 89 tens
Hope this helps :)
