Answer:
100
Step-by-step explanation:
so in this example, you are rounding to the nearest hundred so you are looking if your number is closer to the lowest 100 or the higher 200- so in this case 100 as the lowest and 200 as the highest.
the rule is, if your number ends in 0-4, it stays on the floor, therefore goes to the lower number, 5-9 stays in the sky, so it goes to the higher number.
in this example you are looking at the tens column if the number (30, 40, 50) your tens number is 30 therefore falls into the 0-4 column as 3 is smaller than 4.
Worked example:
130
deciding between; 100 or 200
say the rule: 0-4 stays on the floor, 5-9 stays in the sky
you look at the tens column, the 3 is smaller than 4 so it stays on the floor
therefore 130 is closer to 100
if this does not work for you, you can always subtract 130 from 200 to see if that number is bigger than the distance between 130 and 100.
worked example:
distance between 100 - 130 : 130 - 100 = 30
distance between 130 - 200 : 200 - 130 = 70
30 is the smaller number there you pick 100.
