math question>>estimate answer to:
98+46 tell the strategy you use
Since 98 is almost 100 and 46 is just over 45, add the two underlined numbers in your head.
i get that part, but then they ask what strategy i used
I think the strategy used is to round the numbers to the closest number that's easy to add in your head.
IT'S CALLED ESTIMATE USING ROUNDING
3/16+11/12
To estimate the sum of 98 and 46, we can use a rounding strategy called "rounding to the nearest tens." Here's the step-by-step process:
1. Look at the unit's place of each number. Since 98 ends in 8 and 46 ends in 6, we can round them both to the nearest tens.
2. The nearest tens for 98 is 100 because it is closer to 98 than 90.
3. The nearest tens for 46 is 50 because it is closer to 46 than 40.
4. Add the rounded numbers: 100 + 50 = 150.
Therefore, the estimated answer to 98 + 46 is 150.
