Hello! So Sophia cuts two pieces of ribbon that are different lengths and lines them up together. To find the total length of the two ribbons, let's add them up. Because there is no digit in the thousandths place, we'll fill that in with a zero. Now, let's add up the numbers. 9.281 + 7.740 = 17.021. There. The total length of the ribbons is 17.021 cm long.
We have the number here are 3 3/8 and 2 1/6 by using the first method, multiplying 3/8 with 3/3 and 1/6 with 4/4 we get 9/24 and 4/24 so, 3 9/24 + 2 4/24 = (3+2) and (9/24 + 4/24) when adding 3 and 2 we get 5 and adding 9/24 and 4/24 we get 13/24 so the answer is 5 and 13/24
