Identify the which property does have the same invertendo property 5:10:: 2:4
a) 5:10 = 4:2
b) 10:5= 2:2
c) 5:10 ≠ 2:4
d) 10:5 = 4:2
If a:b :: c:d
then b:a :: d:c that is if two ratio’s are equal then their inverse ratio’s are
also equal.
If 5:2y::7:x select invertendo property:
a) 2y:7 = 5:x
b) 2y:5 = x:7
c) 5:7 = 2y:x
d) 2y:5 = 7:x
If two ratio are equal then there inverse ratio’s are also:
a) equal
b) equal to zero
c) equal to componendo
d) equal to alternendo
Identify the which property does have the same invertendo property 5:10:: 2:4
a) 5:10 = 4:2
b) 10:5= 2:2
c) 5:10 ≠ 2:4
d) 10:5 = 4:2
Componendo property
If a:b = c:d then (a+b):b:: (c+d):d
4:5 = 8:10 identify the componendo property:
a) (4+10): = (8+10)10
b) 9:5:: 28:10
c) (4+4):5 = (8+8):10
d) (4+5):5::(8+10):10
