First you need to make 3 1/2 into a improper fraction so you multiply 3 x 2 and then add 1 which is 7/2. Next you need to divide it by 5/8. So to divide fraction you have to do K.C.F. (Keep, change, flip). So you keep the 7/2 change the division symbol to a multiplication symbol. and then flip the 5/8 into 8/5. So the whole problem would be 7/2 x 8/5. next you just multiply.

7 x 8 = 56

2 x 5 = 10

next you just need to simplify into the smallest fraction and you can simplify both by 2. So 56 / 2 = 28 and 10 / 2 = 5. That's how the solution is 28/5.

Also, the value of the expression 5 x 8/5 is 25/8.

Answer:

make 3 1/2 into a improper fraction by multiplying the 3 and the 2 in the denominator together and then add 1 in the numerator to get 7 then make it 7/2 since the 2 was the denominator in the mixed fraction. Then keep the 7/2 the same turn the division symbol to a multiplication symbol then turn the 5/8 into 8/5 by flipping it then multiply. 7×8= 56 2×5=10 now you have 56/10 so you need to simplify. 2 is common between 56 and 10 so you multiply 56/10 and 2 together. 56÷2= 28 and 10÷2= 5 so now it is 28/5.
