Clare had 400 apples and some oranges. She used 1/5 of her oranges to make fruit punch. In the end, the ratio of the apples and oranges is 5:8. Whats is the ratio of the number of apples and numbers of oranges at first?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Total no. of Apples Clare had = 400
Let's assume that she had total oranges = x
Since,
She used 1/5 of the total oranges =
Hence,
She is left with = oranges .
Now, in the end,
Ratio of the apples to the oranges =
Hence,
No. of apples = 5y
and, No. of oranges = 8y
Now,
We know: 5y = 400
y = 80
Hence,
No. of Left out oranges:
