7 hundreds + 2 tens = 700 + 20 = 720
7 hundreds + 2 ones = 700 + 2 = 702
7 hundreds + 4 tens = 700 + 40 = 740
7 hundreds + 7 ones = 700 + 7 = 707
If we arrange in ascending order, we get 702 < 707 < 720 < 740.
(or)
'7 hundreds + 2 ones' < '7 hundreds + 7 ones' < '7 hundred + 2 tens' < '7 hundreds + 4 tens'
