7 and 10
The simplest answer is 1 and 70. There an infinte number of other pairs.
70 Percent of 100 is 70 To work out the percentage of a number (eg. 100) you devide it by 100 and multiply the result by the percentage you want: 100 / 100 = 1 1 x 70 = 70 Or you can multiply a number by, the percentage you want divided by 100 (Move the decimal place two places to the left) to find the percentage of a number. so to find 70% of a number multiply it by 0.7 to find 50% of a number multiply it by 0.5 (notice that it's half) to find 12.5% of a number multiply it by 0.125 And so on.
One trick for multiplying by 12 is to multiply the number by 10 and then add two times the number. For example, if you want to multiply 7 by 12, first multiply 7 by 10 to get 70, and then add 7*2=14 to get 84.
Multiply the number by 1.7
multiply by 0.7

To find 70% or a number take the number and multiply it by .7
63 and 65 are the number
multiply the number by .7, that is 70 % of that number
Multiply the number by 1.7
One trick for multiplying by 12 is to multiply the number by 10 and then add two times the number. For example, if you want to multiply 7 by 12, first multiply 7 by 10 to get 70, and then add 7*2=14 to get 84.
To get 70% of a number, multiply that given number to the decimal equivalent of 70% which is 0.7. Example: 70% of 5 = 0.7 * 5 = 3.5
multiply by 0.7
70*2
HCF(140, 490) = 70 So 70 and any factor of 70 will do.
Part 15 by 70 and you get 0.21428(...). Seeing as a percentage is a number out of 100 instead of 70, if you multiply 0.21428(...) by 100, you get the percentage: 21.43 % (rounded up to two digits after the period).
