Answer 1

[11] B. 6

1 * 3 = 3, so 2 * 3 = 6

[12] A. 3

20 / 5 = 4, so 15 / 5 = 3

[13] B. 7

2 * 2 = 4, so 7 * 2 = 14,

[14] A. direct proportion

We can figure this out using 150:2 = x:3, which is a direct proportion because y is constant directly with x

-> Not 100% sure on this one

[15] C. partitive proportion

A proportion such as 1:2:3 is more specifically known as a partitive proportion, so this answers the question

[16] B. inverse proportion

As more painters are added, the time that is taken to paint the house decreases, so this is an inverse proportion

-> Not 100% sure on this one

[17] C. 1400 cupcakes

-> 2 weeks = 14 days

-> solve with 200:2 = x:14

-> 2*7 = 14, so 20 * 7 = 1,400

[18] D. 153

-> Putting it simpler, 2:3:3 = Grade 4: Grade 5: Grade 6

-> We are looking for Grade 6

-> 2x + 3x + 3x = 408

-> 8x = 408

-> x = 51

-> 3x = 3(51) = 153

[19] C. 16 hours

-> We can solve with 6:10 = 10:x

-> 10/6 = $\frac{5}{3}$, so 10 * $\frac{5}{3}$ = 16.666666, or for here 16 hours

[20] D. Php 750

-> Put simpler, Mark:Justin:David = 4:5:6

-> 4:5:6 = 4x:5x:6x

-> 5x = 250 which becomes 250 / 5 = 50

-> 4*50 = 200 & 6*50 = 300

-> 200 + 300 + 250 = Php 750

Have a nice day! - Note: not exactly sure on the wording for 14 & 16

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
