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.
4 tens + 9 ones 3 tens + 19 ones 2 tens + 29 ones 1 ten + 39 ones 49 ones.
