Answer:

70/100.

Step-by-step explanation:

When adding fractions, you need to find a common denominator.

This just means that the numbers at the bottom of both fractions you are adding must be the same.

So for 19/100 + 1/10, you need to match the two denominators (bottom numbers).

To do this, you need to multiply 10 by 10 to get 100.

What you do to the bottom, you must always do to the top as well.

So multiply 7 by 10 and get 70.

70/100 will replace 7/10.

Now you can add fractions because the bottom numbers are the same.

2. Alana needs to sell 52 boxes of cookies:

She sold 7 boxes to her aunt

She sold 2 boxes to her mother

She sold 15 boxes to her neighbor

you add 7+2+15 = 24 boxes of cookies that she sold

We need to find out how many more boxes of cookies she needs to sell-

We take the 24 boxes she sold and subtract from 52 boxes that she needs to sell.

24 - 52 = 30

The answer is 30, she needs to sell 30 more boxes.

4. Jamila spent $33.00 and Akiko spent $ 42.00  

Jamila  had 4 times as much money left as Akiko. How much money did each of them have in the beginning?

Since Akiko spent the highest amount- you will have to go with the higher amount to find the answer

4 x $42.00 = $168.00

They both in the beginning had $168.00

I hope this helps.
