Equivalent fractions are produced when the numerator and denominator are multiplied or divided by the same number. 3/5 is therefore an equivalent fraction to :- 6/10 (x 2) 9/15 (x 3) 12/20 (x 4) 15/25 (x 5).......and so on.
Finding 15 percent of a number is equivalent to multiplying the number by 0.15. For example, 15 percent of 200 is equal to 200 x 0.15 = 30.
0.15 x 10 = 1.5 0.15 x 100 = 15 0.15 x 1,000 = 150
2*log(15) = log(x) 152 = x; its equivalent logarithmic form is 2 = log15 x (exponents are logarithms) then, it is equivalent to 2log 15 = log x, equivalent to log 152 = log x (the power rule), ... 2 = log15 x 2 = log x/log 15 (using the change-base property) 2log 15 = log x Thus, we can say that 152 = x is equivalent to 2*log(15) = log(x) (equivalents to equivalents are equivalent)
x+15
Multiply numerator and denominator by 2 to get an equivalent fraction: 7 x 2 15 x 2 = 14 30 Multiply numerator and denominator by 3 to get an equivalent fraction: 7 x 3 15 x 3 = 21 45 Multiply numerator and denominator by 4 to get an equivalent fraction: 7 x 4 15 x 4 = 28 60 Multiply numerator and denominator by 5 to get an equivalent fraction: 7 x 5 15 x 5 = 35 75 Multiply numerator and denominator by 6 to get an equivalent fraction: 7 x 6 15 x 6 = 42 90 Multiply numerator and denominator by 7 to get an equivalent fraction: 7 x 7 15 x 7 = 49 105 Multiply numerator and denominator by 8 to get an equivalent fraction: 7 x 8 15 x 8 = 56 120 Multiply numerator and denominator by 9 to get an equivalent fraction: 7 x 9 15 x 9 = 63 135 Multiply numerator and denominator by 10 to get an equivalent fraction: 7 x 10 15 x 10 = 70 150 Multiply numerator and denominator by 11 to get an equivalent fraction: 7 x 11 15 x 11 = 77 165 Multiply numerator and denominator by 12 to get an equivalent fraction: 7 x 12 15 x 12 = 84 180 Multiply numerator and denominator by 13 to get an equivalent fraction: 7 x 13 15 x 13 = 91 195 Multiply numerator and denominator by 14 to get an equivalent fraction: 7 x 14 15 x 14 = 98 210 Multiply numerator and denominator by 15 to get an equivalent fraction: 7 x 15 15 x 15 = 105 225
To take a percentage of a number, multiply the number by the decimal equivalent of the percentage, which is the percentage divided by 100. 25 percent of 15 = 15 x 0.25 = 3.75
15 increased by two times a number x
x-15, x represents the unknown number, and to have 15 less you would simply subtract 15 from x.... therefore your answer is x-15
Suppose the number is x. then x + 15 = 4*x subtract x from each side: 15 = 3*x divide both sides by 3: 5 = x
14
It is: 7*(8*15) = 840
