Replace the ? with one of the following symbols ($<,>,=$, or $\neq$ ).
$4+3+7 ? 7+0+7$
A) <
B) >
C) =
D) $\neq$
Answer (1)
Calculate the left side of the expression: 4 + 3 + 7 = 14 .
Calculate the right side of the expression: 7 + 0 + 7 = 14 .
Compare the two sides: 14 = 14 .
The correct symbol is equals: = .
Explanation
Calculate both sides of the expression We are given the expression 4 + 3 + 7 ? 7 + 0 + 7 and we need to replace the ? with one of the following symbols: ,="> < , > , = , or = .
First, let's calculate the value of the expression on the left side of the question mark: 4 + 3 + 7 = 14
Next, let's calculate the value of the expression on the right side of the question mark: 7 + 0 + 7 = 14
Now, we compare the two values. Since 14 = 14 , we replace the question mark with the equals symbol, = .
Determine the correct symbol Since both sides of the expression are equal, the correct symbol is = .
Examples
In everyday life, we often need to compare quantities to make decisions. For instance, if you're buying groceries, you might compare the total cost of items from two different stores to decide where to shop. If the total cost at Store A is $4 + 3 + 7 = $14 and the total cost at Store B is $7 + 0 + 7 = $14, then the costs are equal, and you might choose the store based on other factors like convenience or product quality. This simple comparison helps in making informed decisions.
