Combine like terms to create an equivalent expression. 2/5m-4/5-3/5m
Alex17521 [72]

The equivalent expression of \frac{2}{5}m-\frac{4}{5}-\frac{3}{5}m is \frac{-1}{5}m-\frac{4}{5}

Step-by-step explanation:

We need to combine like terms to create an equivalent expression. The given expression is: \frac{2}{5}m-\frac{4}{5}-\frac{3}{5}m

Like terms:

Like terms are those terms that have the same variables and same exponents.

In the given expression 2/5 m and -3/5 m are like terms.

Combining like terms:

\frac{2}{5}m-\frac{4}{5}-\frac{3}{5}m

=\frac{2}{5}m-\frac{3}{5}m-\frac{4}{5}

=\frac{2-3}{5}m-\frac{4}{5}

=\frac{-1}{5}m-\frac{4}{5}

The equivalent expression of \frac{2}{5}m-\frac{4}{5}-\frac{3}{5}m is \frac{-1}{5}m-\frac{4}{5}

Which is greater than 1/7 or 4/6
Alex Ar [27]

Answer:

4/6

Step-by-step explanation:

you multiply until both numbers have the same denominator so 1/7 times 6/6 equals 6/42 and multiply 4/6 times 7/7 it would be 28/42 so the answer would be that 4/6 is greater.
