The mass of earth is approximately 7.97×10 24kilograms. The approximate mass of Venus is 417,000,000,000,000,000,000,000. About how many times greater is the mass of earth than the mass of Venus?

19 47/417

Step-by-step explanation:

7.97×10 24 = 7970000000000000000000000

Simplify the following:

7970000000000000000000000/417000000000000000000000

The gcd of 7970000000000000000000000 and 417000000000000000000000 is 1000000000000000000000, so 7970000000000000000000000/417000000000000000000000 = (1000000000000000000000×7970)/(1000000000000000000000×417) = 1000000000000000000000/1000000000000000000000×7970/417 = 7970/417:

7970/417 conver to mixed fraction

Convert to a mixed number:

7970/417

Divide 7970 by 417:

417 | 7 | 9 | 7 | 0

417 goes into 797 one time. Multiply, subtract, then bring down the next digit:

| | | 1 | |  

417 | 7 | 9 | 7 | 0 |  

- | 4 | 1 | 7 | |  

| 3 | 8 | 0 | 0 |  

417 goes into 3800 nine times. Multiply and subtract:

| | | 1 | 9 |  

417 | 7 | 9 | 7 | 0 |  

- | 4 | 1 | 7 | |  

| 3 | 8 | 0 | 0 |  

- | 3 | 7 | 5 | 3 |  

| | | 4 | 7 |  

The quotient is 19 (the number on top of the bracket) and the remainder is 47 (the number at the bottom of the grid):  

| | | 1 | 9 | (quotient)

417 | 7 | 9 | 7 | 0 |  

- | 4 | 1 | 7 | |  

| 3 | 8 | 0 | 0 |  

- | 3 | 7 | 5 | 3 |  

| | | 4 | 7 | (remainder) invisible comma  

7970 = 19×417 + 47

The quotient of 7970/417 is 19 with remainder 47, so:

19 47/417
