Question

0,7 . 2\(\dfrac{2}{3}\) . 20.0,375.\(\dfrac{5}{28}\)

Answer 1

7/10 * 8/3 * 20 * 3/8 * 5/28

= (7/10 * 20) * (8/3 * 3/8) * 5/28

= 14 * 1 * 5/28

= 14 * 5/28

= 5/2

Answer 2

0,7. 2\(\dfrac{2}{3}\) . 20. 0,375. \(\dfrac{5}{28}\) 

= \(\dfrac{14}{15}\) . 20. \(\dfrac{15}{224}\) 

= \(\dfrac{56}{3}\) . \(\dfrac{15}{224}\) = \(\dfrac{5}{4}\)

Answer 3

= 7/10 x 8/3 x 20 x 375/1000 x 5/28
= 7/10 x 8/3 x 20 x  3/8 x 5/28 
= ( 7/10 x20)x(8/3x3/8)x5/28
=14 x 1 x 5/28
= 14 x 5/28
= 5/2
