the answer is 14. 28/14 = 2 42/14 = 3 70/14 = 5
3X - 4 = 66 add 4 to each side 3X - 4 + 4 = 66 + 4 3X = 70 divide each sides integers by 3 (3/3)X = 70/3 X = 70/3 ------------------check in original equation 3(70/3) - 4 = 66 210/3 - 4 = 66 70 - 4 = 66 66 = 66 ---------------checks ( naturally, you could have canceled here, 3(70/3) and just got 70 )
Use a factor tree. 70 Divide by two. 35,2 Divide by five. 7,5,2 Stop. All the factors are prime. 2 x 5 x 7 = 70

The idea is to divide 210 / 3.
This is a simple question of fractions that is taught in third grade. You first divide 7 into 70 and then multiply the result by 3. It can be written '3/7 x 70'.
40
It is 3/7 because if you divide 30/70 by 10 because thats its highest common factor, then its 3/7.
2 * 70 - 9 / 3 + 8= 140 - 3 + 8= 140 - 11= 129
70
the answer is 14. 28/14 = 2 42/14 = 3 70/14 = 5
Divide each part by 3 and you will get 23 over 70.
Well, darling, 20 goes into 70 a total of 3 times with a remainder of 10. Simple math, really. Just divide 70 by 20 and you'll get your answer. Hope that clears things up for you, honey.
To find the average of a set of numbers, you add up all the numbers and then divide by the total count of numbers. In this case, the sum of 65, 75, and 70 is 210. Since there are three numbers in the set, you divide 210 by 3 to get the average, which is 70.
Its 2/3. Divide each side by 35.
