 Multiply a decimal by a power of ten To multiply by a power of ten, move the decimal point to the right one place for each zero. Multiply 100 x 0.48 Count the zeroes in 100. There are 2 zeroes in 100. Start with 0.48. Move the decimal point 2 places to the right. 0.48 → 48 Write the answer: 100 x 0.48 = 48 Multiply 5.5 x 10 Solution:
