Answer:

8/15

Step-by-step explanation:

the denominators are different so you need to find the lowest common multiple which is 15

you times 3 by five so you have to change the 1 into 5

you times 5 by three so you have to change the other numerator to 3

so it becomes:

5/15 + 3/15= 8/15

I don't get it can u help me??
andrew-mc [135]

Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.

Hope this helps! Let me know if you have any more questions!
