Answer 1

1

Step

Multiple both numerator and both denominator

`(3)/(5)\text{ x }(2)/(9)\text{ = }\frac{3\text{ x 2}}{5\text{ x 9}}\text{ = }(6)/(45)\text{ = }(2)/(15)`

2

`(5)/(6)\text{ x }(4)/(7)\text{ = }\frac{5\text{ x 4}}{6\text{ x 7}}\text{ = }(20)/(42)\text{ = }(10)/(27)`

3

`(3)/(10)\text{ x }(5)/(6)\text{ = }\frac{3\text{ x 5}}{10\text{ x 6}}\text{ = }\frac{15}{60\text{ }}\text{ = }(1)/(4)`

4

`(6)/(7)\text{ x }(7)/(15)\text{ = }\frac{6\text{ x 7}}{7\text{ x 15}}\text{ = }(42)/(105)\text{ = }(2)/(5)`
