5/8 - 3/10

Find the common denominator:

Multiples of 8: 8, 16, 24, 32, 40 (8 x 5 = 40)

Multiples of 10: 10, 20, 30, 40 (10 x 4 = 40)

5/8 = 5*5 / 8*5 = 25/40

3/10 = 3*4 / 10 *4 = 12/40

Now you have 25/40 - 12/40

25 -12 = 13

Answer = 13/40

The answer is A.

jonny [76]

Answer:

x = 5

Step-by-step explanation:

Step 1: Subtract 5 from both sides.

$x + 5 - 5 = 10 - 5$
$x = 5$

Step 2: Check if solution is correct.

$5 + 5 = 10$
$10 = 10$

Therefore, x = 5.
