1.10-1.00= .10
.10÷2=.05
Erasers is .05
Explain the division of 2? I don't understand that

Answer 1

Answer: the erasers value is .05 and 2 are equal to .10

Step-by-step

Answer 2

The cost of the eraser is equal to $\ 0.05$.

What is cost?

" Cost is defined as the amount paid for a purchasing any quantity."

According to the question,

Given,

Total cost of pencil and eraser $= \ 1.10$

$'x'$ represents the cost of a eraser

$'x+ 1'$ represents the  cost of a pencil

As per the given condition of cost, equation we get,

$x+ x+ 1 = 1.10\\\\\implies 2x= 1.10 -1\\\\\implies 2x = 0.10$

Explanation for the division of  $2$,

$x = \frac{0.10}{2}\\ \\\implies x = \frac{1}{2 \times 10} \\\\\implies x = \frac{0.5}{10}\\ \\\implies x = 0.05$

Hence, the cost of the eraser is equal to $\ 0.05$.
