Step-by-step explanation:
2t/r=d cross multiply
2t=rd
t=rd/2
6x² + 12x - 21
3(2x² + 4x - 7)
2x² + 4x - 7 ⇒ This is the factorised answer
This is how you solve it:
Well, ratios are basically fractions. There are 12 boys, so the ratio is 12/25. Since 25 - 12 is 13, there are thirteen girls, so the ratio of girls to student is 13/25.
