Subtract. 7/10 4/5=_____

Find Common Denominator: Find a common denominator for 7/10 and 4/5. The least common denominator (LCD) for 10 and 5 is 10. We need to convert 4/5 to a fraction with a denominator of 10 to subtract it from 7/10. 4/5 = (4*2)/(5*2) = 8/10Convert Second Fraction: Subtract the two fractions with the common denominator. Now that both fractions have the same denominator, we can subtract their numerators. 7/10 - 8/10 = (7-8)/10 = -1/10Subtract Fractions: Simplify the result, if necessary. The fraction -1/10 is already in its simplest form, so no further simplification is needed.

_____

Find Common Denominator: Find a common denominator for $\frac{7}{10}$ and $\frac{4}{5}$ . The least common denominator (LCD) for $10$ and $5$ is $10$ . We need to convert $\frac{4}{5}$ to a fraction with a denominator of $10$ to subtract it from $\frac{7}{10}$ . $\frac{4}{5} = \frac{(4\times2)}{(5\times2)} = \frac{8}{10}$
Convert Second Fraction: Subtract the two fractions with the common denominator. $\newline$ Now that both fractions have the same denominator, we can subtract their numerators. $\newline$ $\frac{7}{10} - \frac{8}{10} = \frac{7-8}{10} = \frac{-1}{10}$
Subtract Fractions: Simplify the result, if necessary. $\newline$ The fraction $-\frac{1}{10}$ is already in its simplest form, so no further simplification is needed.
