Question

2 + 3/8 x 4/7 =
8/15 : 2/11 + 7/15 : 2/11 =

Answer 1

\(\dfrac{2}{1}+\dfrac{12}{56}=\dfrac{112+12}{56}=\dfrac{122}{56}=\dfrac{61}{28}\)

\(\left(\dfrac{8+7}{15}\right):\dfrac{2}{11}\)

\(1:\)\(\dfrac{2}{11}\)

\(\dfrac{11}{2}\)

Answer 2

\(\dfrac{2}{1}+\dfrac{12}{56}=\dfrac{112}{56}+\dfrac{12}{56}=\dfrac{122}{56}=\dfrac{61}{28}\)

   

 

\(=\left(\dfrac{8}{15}+\dfrac{7}{15}\right)\times\dfrac{11}{2}=\dfrac{15}{15}\times\dfrac{11}{2}=1\times\dfrac{11}{2}=\dfrac{11}{2}\)

Answer 3

2 + 3/8 x 4/7 =61/28
8/15 : 2/11 + 7/15 : 2/11 =11/2

Answer 4

2 + 12/56 = 61/28

( 8/15 + 7/15) : 2/11 = 1 : 2/11 = 11/2

Answer 5

11/2
