Question

a) 0.34
\6) 0.8 x 15
() 12Axy
Ts.
2. Multiply the decimals with the whole numbers and find the one​

Answer 1

Table 1, we are multiplying the decimal 0.2658 by powers of 10. Each time we multiply by a power of 10, the decimal point is moved one place to the right. In Table 2, we are dividing the whole number 265,800. by powers of 10. Each time we divide by a power of 10, the decimal point is moved one place to the left. These patterns occur because a decimal is any number in our base-ten number system, and decimal places change by a factor of 10.

Problem 2: Which is greater: 56.5 x 80 or 8 x 565? Explain your answer.

Analysis: 56.5 x 80 = 56.5 x (10 x 8) = (56.5 x 10) x 8 = 565 x 8

Answer: They are equal.
