You don't need to estimate, it equals 18
7/9 of 225 is 175.
Divide 7 into 291. If it comes out evenly, it's a factor. It doesn't, so it's not.
28 in this case.
Because 25 is the largest number that will divide into both 25 and 75 evenly.
5, 11, 25, 55.
7
7/25 is in the simplified form as there is no common whole number that will divide 7 and 25 evenly (remainder zero)
42/7 = 6
No, 17.5 divided by 25 is equal to 0.7
7 goes into 180 25 times, remainder 5.
To convert 7/25 to a percent, divide 7 by 25 and then multiply by 100. The result is 28%.
The answer depends on what you wish to do with the estimate. If you wanted to divide by 25, I would suggest 175 since 175/25 = 7. If you wanted to add 315 then I would suggest 185 since 185 + 315 = 100 + 85 + 15 + 300 = 100 + 100 + 300 = 500.
0.28. When you are dividing by 25, all you have to do is multiply the numerator (7) by 4, then divide by 100.
The front end estimate is 200. But estimating a single number, in isolation and without context, is a complete waste of time. It all comes down to the context of what needs to be done with the number.If I had to add 179 to 1 trillion, I would estimate it as 0.If I had to add 179 to 0.0000000001, I would use the number as given, or possibly the front end estimate. If I had to divide it by 10, I would estimate it as 180, because 180/10 = 18. If I had to divide it by 25, I would estimate it as 175, because 175/25 = 7.
The percentage for 7 over 25 is 28%. To get this, divide 7 by 25 which equals 0.28. To determine the percentage, merely move the decimal point to the right 2 places.
3X + 7 = 25 subtract 7 from each side 3X + 7 - 7 = 25 - 7 3X = 18 divide each sides integers by 3 (3/3)X = 18/3 X = 6 --------------check in original equation 3(6) + 7 = 25 18 + 7 = 25 25 = 25 -------------checks
It is easy enough to divide by 3, to give the exact quotient as 7.3
