A store was selling 8 mangos for $10 at the farmers market.

Keisha said,
“That means we can write the ratio 10: 8, or $1.25 per mango.”
Luis said,
“I thought we had to write the ratio the other way, 8: 10, or 0.8 mangos per dollar."
Can we write different ratios for this situation? Explain why or why not.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

2.25%.
