Question

У Максима было 50 компакт-дисков с играми. На время каникул он дал Антону 0,3 этого количества, а Вадиму- 0,4 остатка. Сколько дисков осталось у Максима?

Answer 1

50*0,3=15 дисков дал Антону,

50-15=35,

35*0,4=14 дисков дал Вадиму,

50-(15+14)=21 диск остался у Максима

Answer 2

Calculating the Remaining Number of Discs for Maxim

To calculate the remaining number of discs for Maxim, we can use the information provided in the question and apply the given percentages to the total number of discs.

1. Calculating the Number of Discs Given to Anton: Maxim gave Anton 0.3 of the total number of discs.

- 0.3 * 50 = 15 discs were given to Anton.

2. Calculating the Number of Discs Given to Vadim: Maxim gave Vadim 0.4 of the remaining discs after giving some to Anton.

- 50 - 15 = 35 discs remaining after giving some to Anton. - 0.4 * 35 = 14 discs were given to Vadim.

3. Calculating the Remaining Number of Discs for Maxim: To find out how many discs are left with Maxim, we subtract the discs given to both Anton and Vadim from the total number of discs.

- 50 - 15 - 14 = 21 discs are left with Maxim.

Conclusion

Maxim has 21 discs remaining after giving 0.3 of the total to Anton and 0.4 of the remaining to Vadim.
