5 1/2+ 3 2/3+ 1 4/5

Mazyrski [523]

Answer:

$10\frac{29}{30}$

Step-by-step explanation:

$5\frac{1}{2} +3\frac{2}{3} +1\frac{4}{5}$

Let us group the integers and the fractions.

$5\frac{1}{2} +3\frac{2}{3} +1\frac{4}{5}$ = $(5+3+1)+(\frac{1}{2} +\frac{2}{3}+\frac{4}{5} )$

= $9+\frac{15+20+24}{30}$

$= 9+\frac{59}{30}$

$=9+1\frac{29}{30}$

$=10\frac{29}{30}$

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

First, notice that we can cancel out an x in the second term. Thus:

$\frac{3x^2}{x^2+x} =\frac{3x^2}{x(x+1)} =\frac{3x}{x+1}$

As with the last question, change the sign to multiplication and "flip" the second term:

$\frac{2x-1}{x+1}\cdot \frac{x+1}{3x}$

Multiply straight across:

$=\frac{(2x-1)(x+1)}{(x+1)(3x)}$

Cancel the (x+1) term:

$=\frac{2x-1}{3x}$

Cannot be simplified further.
