Question

What number is 87 1/2 of 8?

Answer 1

in essence is simply their product, like saying what's 1/3 of 30? well, just (1/3) * (30) = 10, same here.

let's convert the mixed fraction to improper fraction and then multiply them.,

`\stackrel{mixed}{87(1)/(2)}\implies \cfrac{87\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{175}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{175}{2}\cdot 8\implies \cfrac{175}{2}\cdot \cfrac{8}{1}\implies \cfrac{175}{1}\cdot \cfrac{8}{2}\implies \cfrac{175}{1}\cdot 4\implies \text{\LARGE 700}`
