which are the same as the number 68? choose all answers that apply: a 6 tens + 8 tens b 10 + 10 + 10 + 10 c…

Explanation:

Step1: Analyze Option A

6 tens is $6\times10 = 60$, 8 tens is $8\times10 = 80$. Then $6$ tens $+ 8$ tens is $60 + 80 = 140$, which is not equal to 68.

Step2: Analyze Option B (Assuming the option B is incomplete, but if we assume it's a typo and maybe it's 10+10+10+10+10+10 + 8 (since 6 tens is 60 and 8 ones is 8, 60+8=68). Wait, maybe there is a typo in the original problem for option B. Wait, let's re - check. Wait, maybe the user made a typo. But let's check the given options again. Wait, option B as written is "10 + 10 + 10 + 10 -", which is incomplete. But maybe it's a mistake. Wait, let's check option C: 6 ones is $6\times1 = 6$, 8 ones is $8\times1 = 8$, so 6 ones + 8 ones is $6 + 8=14\neq68$. Wait, maybe there is a mistake in the problem options. Wait, maybe option B was supposed to be 6 tens + 8 ones? Wait, the original problem's option B is written as "10 + 10 + 10 + 10 -", which is incorrect. But if we assume that there is a mistake and maybe the intended options are different. Wait, maybe the correct way: 68 is 6 tens (60) and 8 ones (8), so 60 + 8 = 68. Let's re - evaluate each option:

Option A: 6 tens + 8 tens=60 + 80 = 140≠68.

Option B: The expression is incomplete ("10 + 10 + 10 + 10 -"), so we can't evaluate it properly. But if we assume it's a typo and maybe it's 10+10+10+10+10+10 + 8 (6 tens and 8 ones), then it would be 68. But as per the given, it's incorrect.

Option C: 6 ones+8 ones = 6 + 8 = 14≠68.

Wait, maybe there is a mistake in the problem. But if we consider that maybe the options were miswritten. Alternatively, maybe the user intended option B to be 6 tens + 8 ones, but as per the given, none of the options seem correct. But this might be a mistake.

Wait, maybe I misread the options. Let's check again:

Option A: 6 tens + 8 tens=60 + 80 = 140.

Option B: "10 + 10 + 10 + 10 -" is incomplete.

Option C: 6 ones + 8 ones=14.

So, based on the given options, none of them are equal to 68. But this might be a mistake in the problem.

Answer:

None of the options (A, B, C) as given are equal to 68. But if there is a typo in option B, and it's supposed to be 6 tens + 8 ones (i.e., 10+10+10+10+10+10 + 8), then option B would be correct. But as per the given, the options are incorrect.
