To solve these equations and determine the correct placement of commas (zapoyataya), we need to understand the rules for dividing numbers with commas.
Rules for dividing numbers with commas:
When dividing numbers with commas, we need to align the decimal points before performing the division. To do this, we move the decimal point to the right in both the dividend and divisor until the divisor becomes a whole number. We then perform the division as usual.Solution for each equation:
1) 42315 : 4,35 = 105 We move the decimal point in 4,35 to the right once, making it 43,5. Then we perform the division: 42315 : 43,5 = 105.2) 42,315 : 1,05 = 435 We move the decimal point in both 42,315 and 1,05 to the right once, making them 423,15 and 10,5 respectively. Then we perform the division: 423,15 : 10,5 = 435.
3) 42315 : 43,5 = 10,5 No need to move the decimal point in this case. We can directly perform the division: 42315 : 43,5 = 10,5.
4) 4,2315 : 1,05 = 435 We move the decimal point in both 4,2315 and 1,05 to the right once, making them 42,315 and 10,5 respectively. Then we perform the division: 42,315 : 10,5 = 435.
5) 4,2315 : 4,35 = 1050 We move the decimal point in both 4,2315 and 4,35 to the right once, making them 42,315 and 43,5 respectively. Then we perform the division: 42,315 : 43,5 = 1050.
6) 442,25 : 145 = 305 No need to move the decimal point in this case. We can directly perform the division: 442,25 : 145 = 305.
7) 44225 : 3,05 = 14,5 We move the decimal point in 3,05 to the right once, making it 30,5. Then we perform the division: 44225 : 30,5 = 14,5.
8) 4,4225 : 14,5 = 30,5 No need to move the decimal point in this case. We can directly perform the division: 4,4225 : 14,5 = 30,5.
9) 4,4225 : 3,05 = 145 We move the decimal point in both 4,4225 and 3,05 to the right once, making them 44,225 and 30,5 respectively. Then we perform the division: 44,225 : 30,5 = 145.
10) 44225 : 14,5 = 305 No need to move the decimal point in this case. We can directly perform the division: 44225 : 14,5 = 305.
By following these rules and performing the division correctly, we can ensure that the equalities are satisfied and the commas are placed correctly.
