Answer (1)
Let's compare the expressions using the greater than )"> ( > ) , less than ( < ) , or equal to ( = ) symbols.
(a) 7 × 7 ? 50
To compare, we need to calculate each side:
The left side: 7 × 7 = 49
The right side is 50.
Since 49 < 50 , the comparison is: 7 × 7 < 50
(b) 7 × 7 ? 7 × 2
Calculate each side:
The left side: 7 × 7 = 49
The right side: 7 × 2 = 14
Since 14"> 49 > 14 , the comparison is: 7 \times 2"> 7 × 7 > 7 × 2
(c) 0 × 7 ? 7
Calculate each side:
The left side: 0 × 7 = 0
The right side is 7.
Since 0 < 7 , the comparison is: 0 × 7 < 7
(d) 7 + 7 ? 7 × 7
Calculate each side:
The left side: 7 + 7 = 14
The right side: 7 × 7 = 49
Since 14 < 49 , the comparison is: 7 + 7 < 7 × 7
(e) 7 × 1 ? 7
Calculate each side:
The left side: 7 × 1 = 7
The right side is 7.
Since both sides are equal, the comparison is: 7 × 1 = 7
(f) 7 × 8 ? 7 + 8
Calculate each side:
The left side: 7 × 8 = 56
The right side: 7 + 8 = 15
Since 15"> 56 > 15 , the comparison is: 7 + 8"> 7 × 8 > 7 + 8
These comparisons follow basic arithmetic principles, ensuring the steps are clear and easy to understand.
