Looks like 57: 12+9=21, +9=30, +9=39, +9=48, +9=57.
21/30 x 100 = 70. Therefore, 21 is 70 percent of 30.
0.7
0.21 If you want to find what goes into 21 100 times evenly all you have to do is divide 21 by 100.
21
It is the number 1
1,2,3,6
... 3.
Multiply 2100 by 0.3 You can also do it this was- 30% is 30 for each 100- and you have 21 100's. 30 X 21. Or 3X 21 (63) and add a zero.
5 [[ 6 times into 30 and 5 times into 25 ]]
2 goes into 4. 3 goes into 6 or 9. 5 goes into 10, 15, 20, 25, 30. 7 goes into 14, 21, 28.
2
The common factors of 30 and 42 are 1, 2, 3, and 6.
Looks like 57: 12+9=21, +9=30, +9=39, +9=48, +9=57.
40 goes into 870 21.75 times or 21 with remainder 30.
You can't accurately compare fractions if they don't have a common denominator. In other words, the bottom numbers of both fractions have to be the same. To change that, you have to find the LCD, or least common denominator (the smallest number both bottom numbers multiply evenly into.) In this case, the LCD is 30, since 3 is a factor of 30. Since 10 x 3 =30, we have to multiply the top number (or numerator) by 10 also. Here's what the process looks like: 21/30 > 2/3 (original problem) 21/30 > ?/30 (find the LCD) 21/30 > 20/30 (multiply the numerator by the same number as the denominator) 21/30 > 20/30 (final answer) So there you have it. 21 is larger than 20, therefore 21/30 is larger than 2/3.
Every rational number "goes into" every other rational number. In this case, the quotient is 0.7 .
