Question

What do you add to 2 1/8 to make 4

Answer 1

Explanation:

Let us add x to
`2(1)/(8)` to make 4.

`\therefore \: x + 2 (1)/(8) = 4 \\ \\ \therefore \: x + (2 * 8 + 1)/(8) = 4 \\ \\ \therefore \: x + (16 + 1)/(8) = 4 \\ \\ \therefore \: x + (17)/(8) = 4 \\ \\ \therefore \: x = 4 - (17)/(8) \\ \\ \therefore \: x = (4 * 8 - 17)/(8) \\ \\ \therefore \: x = (32- 17)/(8) \\ \\ \therefore \: x = (15)/(8) \\ \\ \therefore \: x =1 (7)/(8) \\ \\ \therefore \:1 (7)/(8) \: should \: be \: added \: in \: 2 (1)/(8) \: to \: \\ \: \: \: \: \: make \: it \: \: 4.`
