Answer:

Estimated answer = 57.0

Exact answer = 54.04

Step-by-step explanation:

Since 19.3 is lesser than 19.5, it will be rounded down to 19.0

Since 2.8 is greater than 2.5, it will be rounded up to 3.0

<u>Estimated multiplication</u>

19.0 * 3.0 = 57.0

<u>Actual multiplication</u>

19.3 * 2.8 = 54.04

<u>Answer:</u>

Estimate = 57

Exact = 54.04

<u>Step-by-step explanation:</u>

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.
