Answer 1

Answer 2

`[8xx10xx5xx9xx7]/[16xx20xx15xx3]`

`=[8xx10xx5xx3xx3xx7]/[8xx2xx2xx10xx5xx3xx3]`

16x20x15x3     8x2x10x2x9x5          2x2               4

 

Answer 4

\(\dfrac{8\times10\times5\times9\times7}{16\times20\times15\times3}\)

\(=\dfrac{1\times1\times1\times3\times3\times7}{2\times2\times3\times3}\)

\(=\dfrac{1\times1\times1\times7}{2\times2}\)

\(=\dfrac{7}{4}\)

Answer 5

= 7/4
