几 (jǐ) and 多少 (duōshǎo) are both words in Chinese that can be translated as "how many" or "how much" in English, but they are used in different contexts and convey slightly different meanings. 几 (jǐ) is usually used to ask about a small quantity, it can be roughly under 10, the number is vague. For example: 你有几个兄弟？ (Nǐ yǒu jǐ gè xiōngdì?) How many brothers do you have? 我这里有几张照片？ (Wǒ zhèlǐ yǒu jǐ zhāng zhàopiàn?) How many photos do I have here? 现在几点？ Xiànzài jǐ diǎn What time is it now? 多少 (duōshǎo) is usually used to ask about a bigger quantity. When the number is not certain but you assume it's definitely more than ten, it's better to ask the question with 多少 (duōshao) instead of 几 (jǐ). For example: 这个东西多少钱？ (Zhège dōngxi duōshǎo qián?) How much does this thing cost? 你的工资多少？ (Nǐ de gōngzī duōshǎo?) How much is your salary? Note that in some contexts, 几 (jǐ) and 多少 (duōshǎo) can be used interchangeably, especially in spoken Chinese. In this case, the choice of word may depend on the speaker's style or emphasis.
