#3**+10 **

thanks Everymornin17,

but 27/100 = 0.27 you do however have the right idea with the n

Thanks Chris,

but $$\frac{43n}{198n}$$ where n is any real non zero number would also work

a=43n and b=198n

a+b=(43+198)n = 241n $$n\ne0$$

if a and b do not have to be integers then this can equal **any real number except for 0**

that is what I think anyway.

#2**+5 **

Write this without the decimal, first = 217

Subtract the non-repeating part from this = 217 - 2 = 215

Write this over a denominator that has the same number of 9s a the repeating digits = 99 and the same number of 0s as the non-repeating digits = 0

So we have

215 / 990 = 43 / 198 {check for yourself that this is equal to the given decimal }

So .... a = 43 and b = 198 and a + b = 241
