in (a) , in what directions and how many places does the decimal point move after finding the product.
Answer (1)
1. Count decimal places:Determine the number of digits to the right of the decimal point in each factor (the numbers being multiplied).2. Sum the counts:Add the counts from step 1. This sum represents the total number of decimal places the decimal point needs to be shifted in the final product.3. Shift the decimal:Starting from the rightmost digit of the whole number part of the product, move the decimal point to the right by the number of places calculated in step 2. Example:Let's say you are multiplying 2.35 (2 decimal places) by 1.2 (1 decimal place). Count: 2.35 has 2 decimal places, and 1.2 has 1 decimal place.Sum: 2 + 1 = 3 decimal places.Shift: If the initial product (before shifting the decimal) is 2820, then shifting the decimal 3 places to the right gives 2.820.Therefore, the decimal point in the product (2.820) moves 3 places to the right compared to the initial position before the shift.
