Question

Define $1:1$ ratio.

Answer 1

A ratio is a mathematical expression written in the form of $a:b$, where $a\mathrm{and}b$ are any integers. It expresses a fraction. The ratio is used to compare the size of two things with the same unit.

Example, In a vegetable basket there are $10$ potatoes and $5$ onions then the ratio of potato to onion can be expressed as

Potato$:$Onion$=10:5$

$=2:1$.

The $1:1$ ratio can be defined as when two quantities are measured, expressed or taken in equal proportions.

Example, In a fruit basked if there are $7$ apples and $7$ oranges then we can say that apple and orange are in the same ratio. That is $1:1$.
