The rectangle area is 98. So if you split it in half, you would get 2 squares. Half of 98 is 49.
If it is now a square, you now simply know, that 7*7=49. Meaning that The sides of the square are 7 each.
7 times the 4 sides equals 28. So the perimeter of one square is 28.
The correct value is -10.
7 plus negative 10 equals negative 3.
Negative 3 times 4 equals -12.
Or, (7+-10=-3•4=-12)
Answer:
Greater than 1: 4/3
Less than 1: 3/4
Step-by-step explanation:
When you divide a number by a smaller number, the result is greater than 1.
When you divide a number by a larger number, the result is less than 1.
For example, look at the numbers 16 and 8.
Divide the larger number by the smaller number, 16/8, and you get 2, which is greater than 1.
Divide the smaller number by the larger number, 8/16, and you get 1/2, which is less than 1.
Now use the numbers in this problem.
4/3 is greater than 1 since you are dividing the larger number buy the smaller number.
3/4 is less than 1 since you are dividing the smaller number by the larger number.
