Multiply 0 . 001 by 0.001 × 5000 . 75

Given, 0 .001 by 0 .001 × 5000 . 75 To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product. 0 .001 × 0 .001 × 5000 . 75 = 0 . 00500075 Hence, the required answer is 0 . 00500075 .

Solve the following: ( 2 . 5 + 3 . 75 ) × 4 . 5

Given, ( 2 . 5 + 3 . 75 ) × 4 . 5 First we will add the decimals, 1 2 . 5 + 3 . 7 5 6 . 2 5 Next we will multiply, 6 . 25 × 4 . 5 = 28 . 125 . Hence required answer is 28 . 125 .

Solve the following: ( 0 . 05 + 3 . 001 ) × 1000

Given, ( 0 . 05 + 3 . 001 ) × 1000 First we will add the decimals, 0 . 0 5 + 3 . 0 0 1 3 . 0 5 1 Next we will multiply, 3 . 051 × 1000 = 3051 . Hence required answer is 3051 .

Solve the following: ( 8 . 57 - 2 . 57 ) × 100

Given, ( 8 . 57 - 2 . 57 ) × 100 First we will subtract the decimals, 8 . 5 7 - 2 . 5 7 6 . 0 0 Next we will multiply, 6 . 00 × 100 = 600 . Hence required answer is 600 .

Solve the following: ( 10 . 57 - 3 . 75 + 0 . 0006 ) × 0 . 001

Given, ( 8 . 57 - 2 . 57 ) × 100 First we will add the decimals, 1 0 . 5 7 + 0 . 0 0 0 6 1 0 . 5 7 0 6 Second we subtract the decimals, 1 0 . 5 7 0 6 - 3 . 7 6 6 . 8 2 0 6 Next we will multiply, 6 . 8206 × 0 . 001 = 0 . 0068206 . Hence required answer is 0 . 0068206 .

Solve the following: 15 . 35 × ( 100 . 50 - 3 . 75 + 903 . 25 )

Given, ( 8 . 57 - 2 . 57 ) × 100 First we will add the decimals, 1 0 0 . 5 0 + 9 0 3 . 2 5 1 0 0 3 . 7 5 Second we subtract the decimals, 1 0 0 3 . 7 5 - 3 . 7 5 1 0 0 0 . 0 0 Next we will multiply, 15 . 35 × 1000 = 15350 . Hence required answer is 15350 .
