To find an expression equivalent to , let's begin by calculating the value:
Performing the calculation:
Next, we check which expression from the provided choices also results in 19.
Let's evaluate each option:
Therefore, the expression equivalent to is given by choice 3: .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Calculate both expressions and see if they give the same result. If and another expression also equals 19, they're equivalent!
Numbers can be deceiving! For example, looks very similar to , but one equals 20 and the other equals 19. Always calculate to be sure.
That's great! Multiple expressions can be equivalent to the same original expression. In math, there are often many ways to write the same value.
Yes! Always calculate each expression to its simplest form (a single number) before comparing. This makes it easy to see which ones match.
Calculate the original expression first: . Then test each choice until you find another expression that also equals 19.
