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
42/7 = 6
7/25 is in the simplified form as there is no common whole number that will divide 7 and 25 evenly (remainder zero)
No, 17.5 divided by 25 is equal to 0.7
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.
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%.
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.
It is easy enough to divide by 3, to give the exact quotient as 7.3
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
