My mother bought 3.64 kg of apples and peaches in the fruit store, of which the quality of apples was 1.6 times that of peaches. How many kilograms of peaches did mom buy? (solution of equations)

My mother bought 3.64 kg of apples and peaches in the fruit store, of which the quality of apples was 1.6 times that of peaches. How many kilograms of peaches did mom buy? (solution of equations)

Suppose that the mother bought a peach of x kg, then the Apple bought 1.6 x kg
x+1.6x=3.64,
  2.6x=3.64,
     x=1.4,
A: Mom bought 1.4 kg of peaches

Mom went to the supermarket to buy fruit. She bought 11kg pear and 8kg apple My mother went to the supermarket to buy fruit. She came to 11 kg pear and 8 kg apple. Their prices were the same. Apples cost 1.2 yuan per kilogram than pears. What's the unit price of apples and pears? What's the unit price ratio?

Pear unit price: 1.2 × 8 × (11-8) = 3.2 yuan
Apple unit price: 3.2 + 1.2 = 4.4 yuan
Pear unit price: Apple unit price = 3.2 ∶ 4.4 = 8 ∶ 11

Discussion on the case of X, y subdivision

Xiaohong bought 3 kg of apple and 5 kg of banana for 24.5 yuan, Xiao Ming bought 7 kg of apple and 3 kg of banana, and spent 31.5 yuan per kg of apple and banana We can't use x, y instead of calculation

3 kg apple and 5 kg banana cost 24.5 yuan; 7 kg apple and 3 kg banana cost 31.5 yuan; 15 kg banana and 9 kg Apple cost 24.5 * 3 = 73.5; 35 g apple and 15 kg banana cost 31.5 * 5 = 157.5 note: 3 kg apple and 5 kg banana cost 24.5 yuan, multiply by 3 to get 15 kg

Mother bought 4 kg of apples and 2 kg of pears, which cost 27.2 yuan. It is known that the price of apples per kilogram is 0.8 yuan higher than that of pears. How much yuan per kilogram of pears?

Apple (27.2 + 0.8x2) / (4 + 2) = 28.8 △ 6 = 4.8
Pear 4.8-0.8 = 4 yuan

Mother bought 2.6 kg of apples and 3.5 kg of pears. The total cost was 20.1 yuan, and 4.5 yuan per kilogram of apples. How much is the price per kilogram of pears

2.6×4.5=11.7
20.1-11.7=8.4
8.4÷3.5=2.4
A: 2.4 yuan per kilogram of pear

Mom bought 10 kilograms of apples and oranges, which cost 39.2 yuan. Can you figure out how many kilograms of apples and oranges each bought? Apple 5.6 yuan per kilogram; orange 2.8 yuan per kilogram

Set to buy Apple x Jin, orange y Jin
X + y = 105.6x + 2.8y = 39.2 simultaneous equations
X = 4, y = 6
So I bought 4 kg apples and 6 kg oranges
