Question

Add

7/27 + 1/18 + 1/10

Answer 1

It would be easier to change these to decimals and then add.

But -- to add them as fractions, you need to find the common denominator, which is 270. (I found that by adding 27 + 27 + 27, etc., until I found a number also divisible by 18 and 10.)

7/27 = 70/270
1/18 = 15/270
1/10 = 27/270

Add the numerators.
