Answer:
3.82 cm tall.
Step-by-step explanation:
Alexander measures a stack of textbooks to be 38.2 cm tall. If there are 10 textbooks in the stack, how tall is each textbook?
From the above question:
1 stack = 10 textbooks = 38.2 cm tall
Hence,
10 textbooks = 38.2 cm tall
1 textbook = x cm
Cross Multiply
10 x = 1 × 38.2
x = 38.2/10
x = 3.82 cm tall
Therefore, each textbook is 3.82 cm tall.
