Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Jumla ya uwiano unaowakilisha idadi ya picha katika galeria ya Malachi ni 10+17=<<10+17=27>>27.
Tofauti katika uwiano unaowakilisha idadi ya picha ambazo Malachi alipiga mwaka huu na mwaka jana ni 17-10=<<17-10=7>>7.
Mwaka huu, Malachi alipiga picha 7/27*2430= 630 zaidi kuliko alivyopiga mwaka jana.
