add 5/8 inch, 11/16 inch, and 27/32 in lowest term ,?

Answer 1

OK, first you need to get everything over a common denominator, and it looks like that will be 32.
So 5/8 = 5*4/(8*4) = 20/32
11/16 = 2*11/(2*16) = 22/32

So, now we add 20/32+22/32 + 27/32
to get
(20+22+27)/32
=69/32
But we need to find out if this is in the lowest terms.
Well, we know 32 has factors of only 2 (it is 2^5).
69, being odd, has NO factors of 2.
We can say that 69/32 = (32*2+5)/32, = 2 and 5/32
