Question

Write a substraction equation with a difference of 54.57.then draw a number line to show between which two whole numbers the difference lies

Answer 1

x-y=54.57

With x as a starting point: x-55<x-54.57<x-54

Explanation:

So, this is a simple equation of two numbers one subtracting from the other equaling to 54.57, we don't know the two numbers so let's call them x and y.

x-y=54.57

Testing any number on x or y we get the other, for example:

y=100:

x-100=54.57

x=54.57+100=154.57

x=100:

100-y=54.57

y=100-54.57=45.43

y=54.57:

x-54.57=54.57

x=54.57+54.57=109.14

x=54.57:

54.57-y=54.57

y=54.57-54.57=0

If we take x as a starting point, y will always be x-54.57, the number line will then be between two whole numbers:

x-55<x-54.57<x-54 (the two whole numbers immediately before and after)

Answer 2

Write a subtraction equation with a difference of 54.57. Then draw a number line to show between which two whole numbers the difference lies.
100 - x = 54.57
