pls I need a answer pls I will brainliest if your answer is correct and if your answer is nonsense i will report you

Using colon

1. 2:18 = 10:60

2. 300:3=400:4

3. 3:5=6:10

4. 39:3=78:6

5. 24:3=32:4

Using fractions

1.2/18 =10/60

2.300/3=400/4

3.3/5=6/10

4. 39/3=78/6

5.24/3=32/4

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

there were a lot of them but the first one to pop up on a google search was bts
