Question

3/4+4/21+7/8+5/7 solve this gution plezzz​

Answer 1

Answer:

$\frac{3}{4} + \frac{4}{21} + \frac{7}{8} + \frac{5}{7}$

$( \frac{3}{4} + \frac{7}{8} ) + ( \frac{4}{21} + \frac{7}{7} )$

$taking \: lcm$

$\frac{(2(3)) +7 }{8} + \frac{4 +(3(7)) }{21}$

$\frac{6 + 7}{8} + \frac{4 + 21}{21}$

$\frac{13}{8} + \frac{25}{21}$

$lcm \: of \: (8 \: and \: 21) \: is \: 168$

$\frac{13(21) + 25(8)}{168}$

$\frac{273 + 200}{168}$

$\frac{473}{168} = 2.81547619$

Answer 2

42*3+4*8+21*7+24*5/168

126+32+147+120/168

425/168
