What is 1 5/12 + 4 1/6 in its simplest form?

Answers

The answer is 5 7/12, here's why:

First convert the mixed numbers into improper fractions to make it simpler to deal with.

1 5/12 = 17/12
4 1/6 = 25/6

Now make them equivalent.

17/12 can stay the same,
25/6 can become 50/12

Now it's just 17/12 + 50/12
Just add the numerators!
17/12 + 50/12 = 67/12

All we have to do from here is simplify 67/12.
12 goes into 67 5 times, with a remainder of 7.
5 becomes the whole number, and our fraction is the remainder (7) over 12.

So 67/12 = 5 7/12.
This is as simplified as the answer can get.

Hope this helps!

Please help I only have today to do this type of work and I'm struggling!! Alice, Raul, and Maria are baking cookies together. They need cup of flour and cup of butter to make a dozen cookies. They each brought the ingredients they had at home. Alice brought cups of flour and cup of butter, Raul brought cup of flour and cup of butter, and Maria brought cups of flour and cup of butter. If the students have plenty of the other ingredients they need (sugar, salt, baking soda, etc.), how many whole batches of a dozen cookies can they make?

A grocery store receipt shows 5% state tax due on laundry detergent and a flower bouquet. Does it matter whether the tax is calculated on each separate item or the total cost? Explain.

Answers

Calculated on each separate item because, the 5% is PER ITEM for example here in Florida, there is a 7% tax but no tax on unprepared food, but if you go to Whole Foods and buy 4 burgers and a head of lettuce they tax for each burger because if it was for the total cost they would be taxing for the head of lettuce which is not what the state law says you can do.
