Mr stand washed 3/8 of his laundry his son washed one third of it who washed most of the laundry how much are the laundry still needs to be washed

Step-by-step explanation:

First you write the 3/8 en 1/3 in another way: In this case, the best way is to write:

3/8 * 3 = 9/24

1/3 * 8 = 8/24

Now you can see the denominators are equal, this will make the question easier.

If we add the fractions, this will make:

9/24 + 8/24 = 17/24

Now, you can see 24 - 17 = 8 ==> 7/24

This means 7/24 of the laundry still needs to be washed

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
