Rational expressions are multiplied and divided the same way numeric fractions are.
The answer is 1000 because 62x4= 248 and then you take 248 and multiply it by 4 and you get 992 then you have to multiply 4x2 which is 8 and then when you add 992+8, you would get 100 ;)
88 times 1.8 would be 158.4! Hope this helps!
