Answer:

1 and 3/20

Step-by-step explanation:

You want to make the denominators the same so you can answer them:

3/4 = 15/20

2/5 = 8/20

You add 15 and 8, which equals 23.

23/20 = 1 and 3/20.

Answer:

The fifth term is 7

Step-by-step explanation:

Please help I am on number 1 please explain

A % is out of a hundred, so you don't need the %/100. Then, you wouldn't do cross multiplication, you would just divide 15/27. Remember, it would be 15/27  because it's percent markup, not the percent the price increased by. So, doing that simple calculation on a calculator you get 0.5555. This converted to a percent is just moving the decimal to the right twice, or multiplied by a 100. That would give you 55.55%, and that's your answer. Make sense?
