Why 1 hundred 4 tens and 14 tens name the same amount.
2 answers:
<span>Because 1 hundred contains 10 tens. So if you are saying 1 hundred and 4 tens it is the same as you would say 10 tens and 4 tens. And if you add them together 10 tens plus 4 tens it will be 14 tens together.</span>
First you need to translate these words mathematically as follows:
1 hundred = 100,
1 ten = 10,
2 tens = 2*10 = 20,
3 tens = 3 * 10 = 30,
4 tens = 4 * 10 = 40,
.
.
10 tens = 10 * 10 = 100
We can express 1 hundred 4 tens and 14 tens as follows:
1 hundred 4 tens = 1 hundred + 4 tens = 100 + 40 = 140 --- (1)
14 tens = 14 * 10 = 140 --- (2)
As (1) = (2), therefore, we can say that 1 hundred 4 tens and 14 tens yield the same amount (which is 140).
