Question

What is 4
`(2)/(7)` · 2
`(1)/(5)`

Answer 1

well, you already know how to convert from mixed to improper, so let's simply do the multiplication, as it's very straightforward.

`\bf 4(2)/(7)\cdot 2(1)/(5)\implies \cfrac{30}{7}\cdot \cfrac{11}{5}\implies \cfrac{30}{5}\cdot \cfrac{11}{7}\implies 6\cdot \cfrac{11}{7}\implies \cfrac{66}{7}\implies 9(3)/(7)`
