1/2 = 8/16
Now we have the same denominator for all our fractions we can add the numerators, so:
7/16 + 7/16 + 8/16 = (7+7+8)/16 = 22/16
We can simplify 22/16 to 11/8 = 1 3/8 (as a mixed number) = 1.375.
1/2+1/4+1/8+1/16 give all the fractions the same denominator =8/16+4/16+2/16+1/16 add them up =12/16+3/16 =15/16 hope it helped (:
i would show my work but that WOULD BE SO BORING so the answer is fifteen over sixteen. 1/2 + 1/4 + 1/8 + 1/16 = gotta convert them all to 16ths. 8/16 + 4/16 + 2/16 + 1/16 = 15/16. later people
its going to be 4over 27 ----
16 + 24/2 = 28/1 or 28
I don't know what visual model is, but 1/2 + 3/16 = 11/16 .
5 + 3 = 8; so 8/16 or 1/2
20 over 16
You don't as first part is 11/16 in its simplest form and second is 3/4 in its simplest form. Add 1/16 to the first part.
0.9375 or 15/16
7 + 2 + 6 + 1 = 16
1 over 2 plus 1 over 2= 2 over 2= 1 whole
2/3 + 1/4 + 2/3 = 4/3 + 1/4 = (16/12) + (3/12) = 19/12 = 1 and 7/12
