First use front end rounding to estimate the answer. then multiply to find the exact answer.

19.3
times 2.8

Estimate = 57

Exact = 54.04

Step-by-step explanation:

We are given two number which we are to estimate by rounding off by front end and then multiply the exact values.

Front end estimate:

19.3 ---> 19

2.8 ---> 3

19 x 3 = 57

Exact multiplication:

19.3 x 2.8 = 54.04

Using front end rounding, we get an estimate of 57 while multiplying the exact numbers we get 54.04.
