Using a calculator I put 1,284/26=49.384615385. Rounded to tenth: 49.4 :)
Answer:
the estimated difference is 4
Step-by-step explanation:
The estimated difference of 12 9/11 - 8 13/15 would be rounding the fractions to a whole number
12 9/11 becomes 12 11/11 which is 13
8 13/15 becomes 8 15/15 which is 9
we rounded each fraction up since each fraction was above the half way mark so the new equation is,
13 - 9 = 4
