danjs · Answer

1 and a half is a rounded up
5 and 4/5 is rounded up

it will be over the real value

danjs · Answer

he used two larger numbers than the original 2, they will end up having a product larger than the real actual product

danjs · Answer

(1+3/7)*(5+4/5) = 58/7 about  8.3

(1 + 1/2)*6 = 9     bigger than the real value

danjs · Answer

not sure how close, is close, for the close estimate
