Question

Joseph wants to estimate 1 3/7 * 5 4/3 To estimate, he simplifies the expression

1 1/2 * 6

Is Joseph’s estimate a close estimate, an underestimate, or an overestimate?

Answer 1

`1 (3)/(7) * 5 (4)/(3) = (10)/(7) * (19)/(3) = (190)/(21) \approx 9,0476..`
When he simplified the expression:

`1 (1)/(2) *6= (3)/(2) * (6)/(1) = (18)/(2) = 9`

`9,047 \approx 9,05 \approx 9`
I think Joseph's estimate a close estimate.
