Answer:
5 tens and 8 ones gives 58
Step-by-step explanation:
We have to describe 58 as a sum of tens and ones
We know that first digit from the right is the ones place
Second digit is the tens place
Hence, 5 tens and 8 ones gives 58
Also, we can see that
10+10+10+10+10=50 (5 tens)
and 1+1+1+1+1+1+1+1=8 (8 ones)
on adding both we get 58
Hence, 5 tens and 8 ones gives 58
