Step-by-step explanation:

Answer 2

Answer: 3/20 or 0.15

Hiii...Yes of course I can

3/5 - 9/20

So here, if we want to add two fractions, we need to make the denominators the same. To make the denominators the same, we use a method known as the LCM Method. Now LCM stands for Least Common Multiple. So to make the denominators the same, we have to find the LCM of 5 and 20. Which means we have to find the least number which is common in both their multiples. so first we will take the big number and see if it is divisible by the other.

5 x 4 = 20

Yes, 20 is is divisible by 5

So the LCM of 5 and 20 is 20

so we need to make both their denominators 20, so we have to multiply the denominator of the first fractiion by 4. But when we multiply a denominator by a number, we also have to multiply the number by the numerator. So

4x3/4x5 = 15/20

=12/20 - 9/20

=12-9/20

=3/20

=0.15

Therefore, the answer is 3/20 or 0.15

Hope this explanation was clear and helpful
