Answer:
17.021 cm long
Step-by-step explanation:
First, you take 7 and add it to 9, and get 16, then you take 0.7 and add it to 0.2 to get 0.9. then after that, you take 16 and add 0.9 to it to get 16.9. Next, you will take 0.04 and add it to 0.08 and get 0.12. You will then add 0.12 to 16.9 and get 17.02 because the 1 tenth added to the 9 tenths equals 1, so really you just take away 0.9 on this part and add 1.02, because of the 2 hundreths. Finally, you will take the 0.001 and add it to the 17.02 and get 17.021.
From the computation, the total length of the two ribbons is 17.021 cm.
From the information given, we are told that Sophia cuts two pieces of ribbon for a craft project. We're given the information that the first ribbon is 7.74 cm long and that second ribbon is 9.281 cm long.
Therefore in order to get the total length, we simply have to add the lengths together. This will be:
= 7.74cm + 9.281 cm
= 17.021 cm
