Use rounding to estimate the product 4 3/4 • 7 2/17
it is NOT about 32 its 35
round the 4 up and the 7 down ... 5 * 7 = ?
Sure! Let's round the given numbers to the nearest whole numbers for an estimate. We can round 4 3/4 to 5 and 7 2/17 to 7. Now let's do some math: 5 times 7 equals 35. So, the estimated product of the rounded numbers is 35. Keep in mind that this is just an estimate, like wearing socks with sandals -- it's not always the best idea, but it gets the job done!
To estimate the product 4 3/4 • 7 2/17 using rounding, we can follow these steps:
Step 1: Convert mixed numbers to improper fractions.
4 3/4 can be written as 19/4.
7 2/17 can be written as 127/17.
Step 2: Multiply the two fractions.
(19/4) • (127/17) = 2413/68.
Step 3: Round the numerator and denominator to a reasonable number of digits.
In this case, we can round 2413/68 to the nearest whole number by rounding the numerator and denominator separately. The numerator of 2413 can be rounded to 2400, and the denominator of 68 can be rounded to 70.
Step 4: Simplify the fraction (if needed).
Since 2400 and 70 are divisible by 10, we can simplify the fraction by dividing both the numerator and denominator by 10.
2400/10 = 240 and 70/10 = 7.
Therefore, the estimated product of 4 3/4 • 7 2/17 is approximately 240/7 or 34.286, after rounding and simplifying.
