Question

fraction question 2 / 3 + 1 / 7​

Answer 1

$\sf{Given \ : \ {\dfrac{2}{3}} + {\dfrac{1}{7}} }$


$\sf{L.C.M. ( 3, 7 ) = 21}$


→ $\sf{ {\dfrac{(2)(7) + (1)(3) }{21}} }$


→ $\sf{ {\dfrac{14 + 3}{21}} }$


→ $\sf{ {\dfrac{17}{21}} }$


$\sf{Hence, \ the \ answer \ is}$ ${\boxed{\sf{\red{ {\dfrac{17}{21}} }}}}$.


# $\sf{L.C.M. = Least \ Common \ Multiple}$

Answer 2

2/3 + 1/7

As the denominators are different we should find the LCMof it

LCM of 3,7= 3×7 = 21

2/3 × 7/7 =14/21

1/7 × 3/3 = 3/21

14/21 + 3/21

17/21

Answer: 17/21
