Если 30рублей принять за 100%,то

30    -   100%

40    -  х  %,

 

х= 100*40/30=133,33333

133,3333-100%= 33,3333

Ответ: груши дороже примерно на 33,3333% чем яблоки

Answer 2

можно составить пропорцию 40-100%      40 =100

30-х%         30    х      100*30/40=75%

100%-75%=25%-больше.

Answer 3

Calculating the Price Difference Between Apples and Pears

To calculate the percentage by which apples are more expensive than pears, we can use the following formula:

Percentage Difference = ((Price of Apples - Price of Pears) / Price of Pears) * 100

Given that 1 kg of apples costs 30 rubles and 1 kg of pears costs 40 rubles, we can calculate the percentage difference.

Using the formula: ((30 - 40) / 40) * 100 = -25%

Conclusion

Based on the given prices, apples are 25% cheaper than pears.
