Answer 1

The following statement is FALSE

Answer 2

 15 : 30 : : 30 : 40 is False

Step-by-step explanation:

Given 15:30::30:40

i.e 15, 30, 30, and 40 are proportional

$\dfrac{15}{30} =\dfrac{1}{2}$

$\dfrac{30}{40} =\dfrac{3}{4}$

so $\dfrac{15}{30} =\dfrac{1}{2}$ $\neq$$\dfrac{30}{40} =\dfrac{3}{4}$

so  15 : 30 : : 30 : 40 is False
