what number is the same as 7 tens and 20 ones

7(10) + 20(1) = 70 + 20 = 90

To find the number that is the same as 7 tens and 20 ones, we can convert the tens and ones into a single number.

First, we multiply the number of tens (7) by 10, since each ten represents a value of 10. So, 7 tens is equal to 7 * 10 = 70.

Next, we add the number of ones (20) to the result of the previous step (70). So, 70 + 20 = 90.

Therefore, the number that is the same as 7 tens and 20 ones is 90.
