Answer

Estimate: 1 The given answer, 1.135, is reasonable.

Work Step by Step

We need to check whether the answer given is reasonable: $54.6\div 48.1=1.135$ We estimate the answer by rounding: $54.6\div 48.1\approx 50\div 50 =1$ We see that the given answer, $1.135$, and the estimate, $1$, are very close. Thus the given answer is reasonable. (We do not need to find the exact answer if the answer is reasonable.)
