Answer:
Explanation:
Basically you just multiply everything together
1) 6.842
2) 2524.691522
3) 4321.4
4) 9370.2
5) 0.0999999
Best way to solve these questions is either a calculator or write the questions down and figure it out yourself. It isn't that hard.
Explanation on how to place the decimal places I found on a good website:
Decimals are multiplied as if they were whole numbers, and then the decimal point is placed in the product.
To find out where the decimal point should be placed, count the number of decimal places after the decimal point in each factor.
Multiply 0.7 by 0.352
0.7 1 decimal place
0.352 3 decimal places
A total of 4 decimal places
Once you have found the sum of the decimal places in each factor, you know how many decimal places the product will need after its decimal point. Starting at the far right of the number, move the decimal point toward the left that number of decimal places.
0.2464 (4 decimal places after the decimal point)
Dividing decimals
1. Move the decimal point in the divisor to the right to make the divisor a whole number.
2. Move the decimal point in the dividend the same number of places to the right.
3. Place the decimal point in the quotient directly over the decimal point in the dividend for the final quotient.
4. Divide as if working with whole numbers
