The 3 values would be 9 , 10 and 11.
because:
48<6(9)
48<54
48<6(10)
48<60
48<6(11)
48<66
300000 all you had to do was round the number down after the 1 significant figure
you round down with
1,2,3,4
and round up with
5,6,7,8,9
so if it asked for 78453
to 2 significant figures you count the numbers and round after that
so 78|453 and since 4 is the next number and it is less that 5 we round down which means it becomes 78000 with is lower than 78453
but if we had 0.0247
and it asked for this number to 2 significant figures all you need to do is count the SIGNIFICANT figures significant means anything with value so that is 1,2,3,4,5,6,7,8,9,10.... 0 has no value therefore we ignore 0 and start counting at the first figure larger than 0
if we go back to 0.0247 that would be the 2 so 2 significant figure of 0.0247 would equal
0.024|7
7 is larger than 5 so we round up to
0.025
tadaa i hope that helped
10 x 10 = 100
20 + 20 + 20 + 20 +20 = 100
4 x 25 = 100
