The product is 1487.9286. Since we're dealing with money, there can Only be 2 numbers after the decimal point, so you'd round it to £1487.93
To estimate you would do 50x30, which equals 1500. That would make it £1500(or dollars or whatever it's the same number).
I think the mixed number would be 1487 pounds and 93 pence (again dollars or whatever it's the same number).
Then the multiply is just the product.
Hope I helped :)
