Answer:
Multiply the divisor by as many 10's as we need, until it is a whole number. Remember to multiply the dividend by the same number of 10's.
Answer:
- Dividing Decimals is similar to dividing whole numbers, except for the way we handle the decimal point. When we divide decimals, we change the divisor to a whole number by moving the decimal point all the way to the right. Then, we move the decimal point of the dividend up to the same number of places to the right and divide the resultant numbers in the normal way as we do regular division.
- Decimals are a part of the extended number system to express tenths, hundredths, thousandths, and so on. Working with decimals may seem a bit complex but the various operations using decimal numbers is quite similar to the operations using whole numbers. A decimal number has a whole number part and the fractional part separated by a dot. The digits following the decimal point show a value smaller than one.
Example 1: Rishi has a collection of marbles that weigh 0.8 grams each. How many marbles does he have if their total weight is 376 grams?
Here, the weight of one marble is equal to 0.8 grams. The total weight of all the marbles together is equal to 376 grams. Thus, to find the number of marbles, we need to divide the total weight by the weight of one marble: 376 ÷ 0.8 = 376 ÷ 8/10 = 376 × 10/8 = 3760/8 = 470.
Therefore, Rishi has 470 marbles.
