use rounding or compatible numbers to estimate the sum 5 x 2 3/5

5 * 2 = 10

My estimate is 13.

I need some help with some compatible dividends in Mrs. Klapperich.

To estimate the sum of 5 multiplied by 2 3/5 using rounding or compatible numbers, we can follow these steps:

Step 1: Round the mixed number 2 3/5 to the nearest whole number.
2 3/5 is approximately equal to 3.

Step 2: Multiply the whole number 5 by the rounded number from step 1.
5 multiplied by 3 equals 15.

Therefore, using rounding, the estimate for the sum of 5 multiplied by 2 3/5 is 15.

To estimate the sum of 5 multiplied by 2 3/5 using rounding or compatible numbers, you can follow these steps:

Step 1: Convert the mixed number to an improper fraction. In this case, 2 3/5 can be written as (5*2 + 3)/5 = 13/5.

Step 2: Choose a compatible number close to 13/5. In terms of rounding or compatible numbers, a compatible number is one that is easy to work with mentally or on paper. In this case, the number 2 or 3 would be a good choice.

Step 3: Multiply the compatible number by 5. If you chose 2 as the compatible number, the calculation would be: 2 x 5 = 10.

Step 4: Multiply the compatible number by the numerator of the fraction (13). Using the compatible number of 2, the calculation is: 2 x 13 = 26.

Step 5: Add the results of steps 3 and 4 together. Using our previous calculations, 10 + 26 = 36.

Therefore, using rounding and compatible numbers, an estimate for the sum of 5 multiplied by 2 3/5 would be 36.
