Answer:
-50%
Step-by-step explanation:
Suppose the fraction is f = p/q before any changes.
Decreasing the numerator by 60% multiplies it by (1 -0.60) = 0.4.
Decreasing the denominator by 20% multiplies it by (1 -0.20) = 0.8.
Then the new fraction is ...
f' = p(0.4)/(q(0.8)) = (p/q)(0.4/0.8) = f(0.5) = f(1 -0.50) = f(1 +(-50%))
The increase in the value of the fraction is -50%.
I have no idea 149 I think lol
Answer:
longest side =33
medium side =19
shortest side = 12
Step-by-step explanation:
Let medium side be x
then longest side =14 +x
shortest side = x-7
we know that ,
perimeter =sum of all side
or, 64 = 14+ x + x + x -7
or, 64 - 7 = 3x
or, 57 = 3x
or, 57÷3 = x
or, x = 19
then
medium side =x = 19
longest side =x+14 =33
shortest side = x- 7 = 12 #
