Answer:
50
Step-by-step explanation:
When rounding to the nearest ten, like we did with 47 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
We use rule A so 7 will go up. This will round the number up to 50.
Hope this helps :D
