Which expression is equivalent to the given equation?
To solve the problem, we need to find an equivalent expression for .
Now, let's verify:
Perform .
Then perform .
Therefore, the expression simplifies to 57, which is the same as the result of .
Hence, the expression is equivalent to .
Therefore, the correct choice is .
Thus, the solution to the problem is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
You can break 9 into any combination that adds to 9! Like 5+4, 7+2, or 8+1. The key is that all parts must be subtracted to keep the expression equivalent.
No, the order doesn't matter for subtraction! gives the same result as because we're subtracting both numbers.
Check that your decomposed parts add up to the original number. Since 6 + 3 = 9, then equals .
Absolutely! This decomposition strategy works great with larger numbers. For example, could become to make mental math easier.
Always double-check by calculating both expressions. Compute directly, then compute your decomposed version. If they don't match, recheck your arithmetic!
