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

### Instruction:
Ralph is going to practice playing tennis with a tennis ball machine that shoots out tennis balls for Ralph to hit. He loads up the machine with 175 tennis balls to start with. Out of the first 100 balls, he manages to hit 2/5 of them. Of the next 75 tennis balls, he manages to hit 1/3 of them. Out of all the tennis balls, how many did Ralph not hit?

### Response:
 Kati ya mipira 100 ya kwanza, Ralph aliyapiga 2/5 yake na hakuyapiga 3/5 yake, 3/5 x 100 = 60 mipira ya tennis ambayo Ralph hakuyapiga.
Kati ya mipira 75 inayofuata, Ralph aliyapiga 1/3 yake na hakuyapiga 2/3 yake, 2/3 x 75 = 50 mipira ya tennis ambayo Ralph hakuyapiga.
Jumla, kati ya mipira yote ya tennis ambayo Ralph aliyapiga, 100 + 75 = 175 jumla, Ralph hakuyapiga mipira 60 + 50 = 110.
