Answer:
multiplicative inverse of 1/2 is 2
Step-by-step explanation:
The multiplicative inverse of a/b is b/a
Because
To get multiplicative inverse of any fraction we take the reciprocal of that fraction
Multiplicative inverse of
2/1 or 2 are same
so multiplicative inverse of 1/2 is 2
Answer:
The ratio of perimeter of ABCD to perimeter of WXYZ =
Step-by-step explanation:
First, we have to determine the multiplicative factor of the dimensions for both figures.
Considering sides AB and WX,
multiplicative factor =
= 1.5
So that:
XY = 6 x 1.5 = 9
YZ = 7 x 1.5 = 10.5
ZW = 7 x 1.5 = 10.5
Perimeter of ABCD = 6 + 7 + 7 + 8
= 28
Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of the two quadrilaterals can be determined as;
ratio =
=
=
The ratio of the perimeter of ABCD to perimeter of WXYZ is .
