What missing number makes the number sentence, 28.02=20+8=?, true?

I think you meant

28.02=20+8+?
since 20+8 = 28
and 28.02-28 = .02,

28.02=20+8+.02

FALSE............

57,865-__+23129=648,274

Nx1\5=2\15

To find the missing number that makes the number sentence true, we need to solve the equation 28.02 = 20 + 8 = ?.

To solve this equation, we can start by adding 20 and 8:

20 + 8 = 28

Now we have:

28.02 = 28

To make 28.02 equal to 28, we need to subtract 0.02 from 28.02:

28.02 - 0.02 = 28

Therefore, the missing number that makes the number sentence, 28.02 = 20 + 8 = ?, true is 0.02.
