Lessons 11-12: Multiplying Decimals
2 x 0.43 = 0.86

Remember, we make copies of hundredths like we make copies of tenths.
Hundredths is a different unit, but we can multiply it just like tenths.
Use your place value chart to find the product of 2 x 0.43. Complete the sentence,
“2 copies of 43 hundredths is _____________.”
Now, read what your place value chart shows.
So, we have 2 groups of 4 tenths and 2 groups of 3 hundredths. I need to combine
tenths with tenths and hundredths with hundredths.
