Question

I have a problem with fractions. 7/7 - 2/5. I am supposed to estimate with compatible numbers.

Answer 1

Using estimation with compatible numbers the solution is;

`(1)/(2)`

Step-by-step explanation:

We want to estimate the fraction below with compatible numbers.

`\begin{gathered} (7)/(7)-(2)/(5) \\ (7)/(7)=1 \\ (2)/(5)\approx(1)/(2) \end{gathered}`

So, by estimation the fraction becomes;

`\begin{gathered} 1-(1)/(2) \\ =(1)/(2) \end{gathered}`

Using estimation with compatible numbers the solution is;

`(1)/(2)`
