Given the equation:
3.7 x 5.1
Determine the product and estimate the decimal places.
Solution:
In multiplying with decimal place, we simply equate the product to the number of decimal place that the factors have, in our case since we 1 decimal place multiplied to 1 decimal place, then the product will have 2 decimal places. Before multiplying, we must simply understand first the concept of multiplying, dividing, or introducing signs. If similar signs are introduced, multiplied or divided to one another, the answer will become positive, hence if the signs are opposite to one another, then the answer will become negative.
= (3.7)(5.1)
= 18.87
Final answer:
= 18.87
