conversations.value: I'm completely lost with this math problem: In his phone gallery, Malachi has the number of selfies he took last year and this year in the ratio of 10:17. If he has 2430 photos in his gallery, how many more photos did he take this year than last year?
  Can you give me a hand?

conversations.value: The total ratio representing the number of photos in the Malachi gallery is 10+17=27
  The difference in the ratios representing the number of photos Malachi took this year and last year is 17-10=7.
  This year, Malachi took 7/27*2430= 630 more photos than he took last year.
