Let's solve the problem step by step. Let's assume the weight of the olive is 'x' grams. According to the given information, the weight of the peach is 7 times the weight of the olive, so the weight of the peach is 7x grams.
We are also told that the peach weighs 900 grams more than the olive. Mathematically, this can be represented as 7x = x + 900.
Now, we can solve this equation to find the weight of the olive:
7x - x = 900
6x = 900
x = 150
Therefore, the weight of the olive is 150 grams. The weight of the peach is 7 times the weight of the olive, which is 7 * 150 = 1050 grams.
To calculate the total weight in kilograms, we need to convert the weights from grams to kilograms:
Weight of the olive = 150 grams = 0.15 kilograms
Weight of the peach = 1050 grams = 1.05 kilograms
So, the total weight of the peach and olive is 0.15 + 1.05 = 1.2 kilograms.
