Well, isn't that just a happy little math question! If you have 7 tens, and you take away 2 tens, you're left with 5 tens. It's like painting a beautiful landscape - just a few simple brushstrokes can create a whole new picture.

17 tens = (10 + 7) tens = 10 tens + 7 tens = 1 hundred + 7 tens.
It is 276.

Two tenths would be notated as .2 and .7 would be seven tenths.
To write 2 tens and 7 tenths as a decimal, first convert each part: 2 tens is 20, and 7 tenths is 0.7. Then, combine them by adding these two values: 20 + 0.7 equals 20.7. Therefore, 2 tens and 7 tenths as a decimal is 20.7.

17 tens = (10 + 7) tens = 10 tens + 7 tens = 1 hundred + 7 tens.

The number that has 9 tens and 7 fewer ones than tens is 83. This is because 9 tens equal 90, and if we have 7 fewer ones than tens, we subtract 7 from the tens place, giving us 90 - 7 = 83. Therefore, the number with 9 tens and 7 fewer ones than tens is 83.
Two tenths would be notated as .2 and .7 would be seven tenths.
The first (left most) digit is the number of tens and the other is the number of ones. So 57 = 5 tens plus 7 ones = 50 + 7 = 57
