No, 30 ones is not the same as 30 tens. In our base-10 number system, each place value is 10 times greater than the one to its right. So, 30 ones is equal to the number 30, while 30 tens is equal to the number 300. The difference in value is due to the positional notation system we use in mathematics.

90 + 7 is not and has never been equal to 70 + 9
In mathematics, the number of tens in a given quantity is determined by dividing the quantity by 10. In this case, if we have 30 ones, we can divide 30 by 10 to find out how many tens are in 30 ones. The result of 30 divided by 10 is 3, so there are 3 tens in 30 ones.
30
Its the same.
Yes, 30 tens is the same thing as 300.
You either have one or two ones.

30+14=44
It's actually how many tenths are in 3 ones The answer is 30
3 tens is equal to the number 30, and 3 ones is equal to the number 3.So, 3 tens and 3 ones is 33; and 67 minus 33 (or 67 less33) is 34.You could also look at the number 67 and see that it is 6 tens and 7 ones. Then it is easier to say "6 tens and 7 ones minus 3 tens and 3 ones = 34"because:6 tens minus 3 tens = 3 tens, and 7 ones minus 3 ones = four ones.3 tens and four ones = 34
3 tens is 30 16 ones is 16 30 + 16 = 46 So the answer is b.
