1 2/5m - 3/5 ( 2/5m + 1 )
Hunter-Best [27]

Answer:

1 4/25 - 3/5, or 29/25 - 3/5, or \frac{(29m - 15)}{25}

it doesn't really matter they all mean the same

Step-by-step explanation:

1 2/5m - 3/5(2/5m + 1)

multiply first

1 2/5m - 6/25m - 3/5

multiply 1 2/5 only so the denominator is 25 as we can't simplify 6/25, it's so we can add them together, we can't add 3/5 tho bc it's a different term so there's no need to multiply that.

1 10/25m - 6/25m - 3/5

add/subtract

1 4/25m - 3/5
