Which one doesn’t show the correct way of breaking apart to find 276-78?
A) 200-78+76
B)276-70-8
The correct answer is A) 200-78+76. This equation does not accurately break apart 276-78.
The option that does not show the correct way of breaking apart to find 276-78 is B) 276-70-8.
To find the difference between 276 and 78, we can break apart the numbers in various ways and perform the subtraction. Let's evaluate the given options:
A) 200-78+76:
In this case, we decompose 276 as 200 + 76. Then, subtracting 78 from 200 gives us 122, and adding 76 results in 198. Therefore, this option correctly breaks apart 276-78.
B) 276-70-8:
With this option, we initially separate 276 as 70 + 206. Subtracting 78 from 70 gives us -8, but when we subtract 8 from 206, we get 198. So, this option also correctly breaks apart 276-78.
Both options A and B show the correct way of breaking apart 276-78, so neither option is incorrect.
