How would you use place value to compare 203, 478 and 204,210

1. Comparison between 203 and 478 using place value

  Unit digit of 203=3, Unit digit of 478 =8→ 8> 3

  Ten's digit of 203=0, Ten's digit of 478 =7,→7>0

Hundred's digit of 203 =2, Hundred's digit of 478=4, → 4>2

As both of them are three digit number and hundred's place of 478 is greater than 203, ⇒478>203

2. Comparison between 204 and 210 using place value

  Unit digit of 204=4, Unit digit of 210 =0→ 4> 0

Ten's digit of 204=0, Ten's digit of 210=1→1>0

Hundred's digit of 204 =2, Hundred's digit of 210=2, →2=2

Both of them are three digit number, hundred's place are same, but ten's digit of 210 is greater than 204 , So ⇒ 210> 204

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
