Which expression has the same value as 59.2 - 84.7?
timama [110]

Answer:

-25.5

Step-by-step explanation:

Hi Baby girl,

59.2 - 84.7 can be worked out this way:

First calculate 84.7 - 59.2 on your rough paper

That gives 25.5

Finally make your answer a negative number (since the question is about subtracting a larger number from a smaller number)

The answer therefore is -25.5

First use front end rounding to estimate the answer. Then multiply to find the exact answer.
iren2701 [21]

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
