Final answer:
By converting the oak leaf's length from mm to cm, we find that the difference between the 7.9 cm oak leaf and the 6 cm maple leaf is 1.9 cm.
Step-by-step explanation:
To find the difference in length between an oak leaf and a maple leaf, we first need to convert the measurements to the same unit. The oak leaf is 79 mm long, which is equivalent to 7.9 cm (since 10 mm = 1 cm). The maple leaf is 6 cm long. Now that both measurements are in centimeters, we can subtract the length of the maple leaf from that of the oak leaf to find the difference.
7.9 cm (oak leaf) - 6 cm (maple leaf) = 1.9 cm
Therefore, the difference in length between the two leaves is 1.9 cm.
