I need help in this question can anyone help me please. A pattern has 4 blue triangles to every 12 yellow triangles. If you were to draw 16 blue triangles, how many yellow triangles would you need?

48 yellow triangles

Step-by-step explanation:

this problem can be represented as a ratio

4b : 12y (4 blue to 12 yellow)

16 blue triangles is 4 more time the amount than the original ratio.

16b : ?y

you can solve this problem by multiplying 12 by 4

12 * 4 = 48

this now means that for the 16 blue triangles, there should be 48 yellow.

16b : 48y

i hope this makes sense to you, and i was helpful.

stay safe!!
