The answer is B. You need to find a common denominator. B) 1/4 - 1/5 = 1/20. To get a common denominator, multiply 5 and 4 to get 20. The common denominator is now 20. Now you have to multiply the numerators by the opposite denominator. This gives you 5/20 - 4/20 which equals 1/20 because you are subtracting the numerators, 5 and 4.

dybincka [34]

Answer:

Yes, he can.

Step-by-step explanation:

To find the sale, you need to times the sale percentage by the original price so

60 x 0.50 = 30

Then you subtract the original price by the sale price so

60 - 30 = 30

So the with the sale, the price is $30.

Now the tax

Do the same

30 x 0.045 = 1.35

Now instead of subtracting you add so

30 + 1.35 = $31.35

Yes, he can afford it.
