Answer and Step-by-step explanation:
To round -52.13 and -20.26 to the nearest ten, we need to look at the digit in the tens place.
For -52.13:
- The digit in the tens place is 5.
- Since 5 is greater than or equal to 5, we round up.
- Rounding up means increasing the digit in the tens place by 1 and changing all the digits to the right to 0.
- So, -52.13 rounded to the nearest ten is -50.
For -20.26:
- The digit in the tens place is 0.
- Since 0 is less than 5, we round down.
- Rounding down means keeping the digit in the tens place the same and changing all the digits to the right to 0.
- So, -20.26 rounded to the nearest ten is -20.
Now, let's estimate the product of -50 and -20:
- Since both numbers are negative, their product will be positive.
- When multiplying two-digit numbers, it can be helpful to round to the nearest ten and then multiply.
- The rounded values are -50 and -20.
- Multiplying -50 and -20, we get 1000.
Therefore, the estimated product of -50 and -20 is 1000.
