=60+40+30+24/120

=154/120

Answer 2

Answer:

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

first we can arranged the same base of these numbers :

2, 3, 4, and 5 is a base so we can calculate The minimum common factor

and the M.C.F is 2X3X4x5

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

$\frac{1}{2} = \frac{1 \times 3 \times 4 \times 5}{2 \times 3 \times 4 \times 5} = \frac{60}{120}$

$\frac{2}{3} = \frac{2 \times 2 \times 4 \times 5}{3 \times 2 \times 4 \times 5} = \frac{80}{120}$

$\frac{3}{4} = \frac{3 \times 2 \times 3 \times 5}{4 \times 2 \times 3 \times 5} = \frac{90}{120}$

$\frac{4}{5} = \frac{4 \times 2 \times 3 \times 4}{5 \times 2 \times 3 \times 4} = \frac{96}{120}$

So, we can sum

$= \frac{60}{120} + \frac{80}{120} + \frac{90}{120} + \frac{96}{120}$

$= \frac{60 + 80 + 90 + 96}{120}$

$= \frac{326}{120}$

$= \frac{163}{60}$

$= 2 \frac{43}{60}$
