Which of numbers π, π, π, and π is one and three-quarters?

We know that one and three-quarters lies between the integers one and two. One and three-quarters is less than two and greater than one. This means that the only possible answers are π and π.

There are three hash marks between each whole number. This means that there are four jumps. Each jump, therefore, represents one-quarter. As π is one mark above one, π is equal to one and a quarter. π is three marks above one or one mark below two. This is equal to one and three-quarters. The correct answer is, therefore, π.

Whilst weβre not asked to in this question, we could also work out the values of π and π. π is a quarter above negative two or three-quarters below negative one. This means it is equal to negative one and three-quarters. π is one-quarter below negative one, so itβs equal to negative one and a quarter. As already stated in this question, the correct answer is π.
