Directions:Multiply (-1/2)(-3/8)
mY ANSWER : .1875 Now how do i turn this into a fraction.
numerator multiplied: 3
denominator multiplied 16
3/16
How do you get to that answer because not every single one would be multiplied by the numerator 3. Can you explain to me how to change a decimal to a fraction.
Actually, your problem started when you converted 1/2 to a decimal and multiplied by 3/8 converted to a decimal. Do it as Bob Pursely has suggested like this.
-1/2 x -3/8.
Multiply the two top numbers together. That is -1 x -3 = +3
Now multiply the two bottom numbers together. That is
2 x 8 = 16.
So the answer is 3/16. Now you don't have the problem of converting a decimal to a fraction.
To convert a decimal to a fraction:
1. Write down the decimal as a fraction with 1 as the denominator. For example, if you have the decimal 0.1875, write it as 0.1875/1.
2. Determine the number of decimal places. In this case, there are four decimal places after the decimal point in 0.1875.
3. Multiply both the numerator and denominator by 10 raised to the power of the number of decimal places. In this case, multiply both the numerator and denominator by 10^4 (since there are four decimal places).
0.1875/1 x 10^4/10^4 = 1875/10000.
4. Simplify the fraction, if possible, by finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by it. In this case, the GCD of 1875 and 10000 is 125.
1875/10000 ÷ 125/125 = 15/80.
Hence, the decimal 0.1875 can be expressed as the fraction 15/80.
