To solve the equation [tex]\( 1 - \frac{3}{10} \)[/tex], we need to subtract the fraction [tex]\( \frac{3}{10} \)[/tex] from 1.
First, note that 1 can be written as the fraction [tex]\( \frac{10}{10} \)[/tex], which makes the subtraction easier to manage:
[tex]\[
1 = \frac{10}{10}
\][/tex]
Now, we perform the subtraction of the fractions:
[tex]\[
\frac{10}{10} - \frac{3}{10} = \frac{10 - 3}{10} = \frac{7}{10}
\][/tex]
So,
[tex]\[
1 - \frac{3}{10} = \frac{7}{10}
\][/tex]
Therefore, the fraction to make the calculation correct is [tex]\( \frac{7}{10} \)[/tex].
