7 3/5 + 3 9/20 show the steps

11   1 /20

Step-by-step explanation:

7 3/5 + 3 9/20

The common denominator is 20

7 3/5 *4/4 = 7 12/20

Add the mixed numbers

 7  12/20

+3  9/20

10  21/20

We have an improper fraction,  subtract 20 and add 1 whole

10+1  1/20

11 1 /20

1 and 1/20

Step-by-step explanation: To add mixed numbers, first add the fractions.

Since 3/5 and 9/20 are unlike fractions, we first need to find a common denominator which in this case is 20.

So we multiply the numerator and denominator of 3/5 by 4 to get 12/20 and 9/20 already has 20 in the denominator.

Now we can add the like fractions, 9/20 + 12/20, to get 21/20.

Next we add the whole numbers. 7 + 3 is 10.

So 7 and 3/5 + 3 and 9/20 is 10 and 19/20.

Now we can write this as the mixed number, 1 and 1/20.

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
