To write a number with a specific number of significant figures, you need to consider the digits in the number and round off if necessary.
a) To write 480 with 1 significant figure, you would round it to the nearest ten. Since the digit in the tens place is 8, which is greater than 5, you would round up to 500.
b) To write 480 with 2 significant figures, you would round it to the nearest whole number. Since the digit in the ones place is 0, which is less than 5, you would round down to 480.
c) To write 480 with 3 significant figures, you would keep the ones place and round the remaining digits. Since the digit in the tens place is 8, which is greater than 5, you would round up. Therefore, 480 would be written as 480.
d) To write 480 with 4 significant figures, you would keep all the digits since there are already 3 digits in the number. Therefore, 480 remains as 480.
