If you want to add or subtract fractions :

1- make sure that the denominators of the fractions are equal. if they are not, then multiply each of them by a number so that they will be equal.

2- add or subtract the numerators.(if you already had multiplied the denominator of a fraction by a number, then you should multiply the numerator by the same number and do the adding or subtracting)

3- simplify it's possible

here are the answers :

$\frac{3}{7} + \frac{6}{11} = \frac{33 + 42}{77} = \frac{75}{77}$

$\frac{1}{3} + \frac{3}{4} = \frac{4 + 9}{12} = \frac{13}{12} = 1 \frac{1}{12}$

$\frac{4}{5} + \frac{3}{7} = \frac{28 + 15}{35} = \frac{43}{35} = 1 \frac{8}{35}$

$\frac{7}{12} - \frac{1}{8} = \frac{14 - 3}{24} = \frac{11}{24}$

$\frac{9}{10} - \frac{2}{3} = \frac{27 - 20}{30} = \frac{7}{30}$

good luck

Savemore National bank starts the day with 2.81 times 10^4 dollars in the vault. At the end of the day, the bank has 3.5 times 1

suter [353]

ANSWER

There is

$3.219\times {10}^{5}$

more money in the vault in the evening than in the morning.

EXPLANATION

The amount of money in the vault in the morning is

$2.81 \times {10}^{4}$

The amount of money in the vault at the end of the day is:

$3.5 \times {10}^{5}$

To find how much more money is in the vault at the end of the day than there was in the morning, we subtract to get:

$3.5 \times {10}^{5} - 2.81 \times {10}^{4}$

$= 3.5 \times 100000 - 2.81 \times 10000$

$350000 - 28100= 321900$

Therefore, there is

$3.219\times {10}^{5}$

more money in the vault.
