Answer:

<h3>Step-by-step explanation: for #2, look at 6 3/4 and make it into a decimal. Do the same to 7 1/2. Compare them both to see which one is shorter by subtracting 6 3/4 from 7 1/2 and when you get your answer for that, make that into a fraction. Predict that 6 3/4 is shorter because of how much less it is compared to 7 1/2. (I hope I helped you in some way. Good luck!)</h3>

Is 10.846 an integer

yulyashka [42]

Hello!

An integer is defined as a number which is not a fraction or irrational. It should be able to be written out as just a number, without a decimal point or additional fraction. (It can have a negative sign) For example, a few integers would be 2, 5, -8, and 9109, while some non-integers would be 3.1, 3 3/2, and 5i.

In this case, 10.846 is not an integer, as it has a decimal.

Hope this helps!

Answer:

4 blue marbles

Skills needed: Number Theory, Fractions

Step-by-step explanation:

1) The problem tells us that the jar contains marbles that are either red, green, or blue (No Other Color).

It also mentions that $\frac{2}{5} (\frac{4}{10})$ of the marbles are red

and that $\frac{1}{10}$ of the marbles are blue

- The given statement is that 20 marbles are green, and we need to find out the number of blue marbles.

2) We need to first find out the total number of marbles, and then multiply that by $\frac{1}{10}$ to get the # of blue marbles.

---> Given $\frac{4}{10}$ are red and $\frac{1}{10}$ are blue, $1-\frac{1}{10}-\frac{4}{10}$ of the marbles are green (since fractions add up to 1 whole)
