Answer:
Option D.
Step-by-step explanation:
In order to resolve this problem, we are going to transform every fraction on a decimal number.
A) is a mixed fraction. To get a proper fraction, we let the denominator as 2, and to get the numerator we multiply 2 by 2, and we add 1, as seen on the attached picture.
So:
We divide 5 by 2 and we get 2,5.
So, the first option is not true, as 1.5 is smaller than 2,5.
B) We divide 1 by 2 and get 0,5. They are equal numbers, we can't say that 0,5 is bigger than 0,5.
C) -2.5 is smaller than -1,5 so this option is not true.
D)
We divide 7 by 2 and we get -3,5. In fact, -3,5 is bigger than -4.5, as there is a major distance from this negative number to cero.
Answer:
Step-by-step explanation:
Important Information:
Perimeter of rectangle=
Method:
The first step to work this out is to multiply the width of 85 by 2, this gives you 170.This is because a rectangle has two sets of equal sides. This means that there two widths.
The next step is to subtract 170 from the perimeter of 364, this gives you 194. This is because the formula for the perimeter of a rectangle is. This means that in order to isolate the values of the lenght we must subtract the values of the width.
The final step is to divide the value of 194 by 2, this gives you 97. This is because that is the value for 2*the length. That means in order to work out the value of 1 you would need to divide by 2.
Step By Step:
1) Multiply 85 by 2.
2) subtract 170 from 364.
3) Divide 194 by 2.
