Six oranges are equal to one pear and three apples, and one pear is equal to one apple and two oranges. How many oranges are equal to the weight of one apple? I'm in the third grade. I want the formula, not the equation!

Six oranges are equal to one pear and three apples, and one pear is equal to one apple and two oranges. How many oranges are equal to the weight of one apple? I'm in the third grade. I want the formula, not the equation!

6 oranges = 1 pear + 3 apples
1 pear = 1 Apple + 2 oranges
So: 6 oranges = 1 Apple + 2 oranges + 3 apples
6 oranges = 4 apples + 2 oranges
Subtract two oranges from both sides:
4 oranges = 4 apples
1 orange = 1 apple

A total of 320 kg of oranges, apples and pears were delivered to the store. The ratio of oranges to apples is 5:6, and the weight of pears is 3 / 10 of that of apples. How many kg more oranges than pears

This problem can be solved by setting an unknown number. First, let the weight of the apple be XKG, the weight of the pear be 3 / 10xkg, and the weight of the orange be 5 / 6xkg. In this way, x + 3 / 10x + 5 / 6x = 320 can get x = 150, that is, the weight of the apple is 150kg. From this, we can know that the weight of the pear is 150 * 3 / 10 = 45kg, and the weight of the orange is 150 * 5 / 6

One apple is equal to the weight of two peaches. The weight of two apples is greater than that of three pears. Please arrange the weight of apples, pears and peaches
I don't think pears and peaches can be compared because only four peaches weigh more than three

The landlord's understanding is correct`
