WebSolution: x 2 y 3 /xy 3 In both numerator and denominator, xy 3 is the common term. So cancelling the like terms we get; x 2 y 3 /xy 3 = x How to Divide Numbers with Decimals While dividing numbers with decimals, we can observe the decimal point in the divisor. As we know, there should not be decimals in the divisor. WebIf you want to use two different laws of exponents, you can use the negative exponent rule, if you move an exponent from numerator to denominator (or from denominator to numerator), you have to change the sign. So 12^-5 in the denominator would be the same as 12^5 in the numerator and x^5 in the denominator would be x^-5 in the numerator. flashairfwupdatetoolv2

Why do we have to divide 4320 by 3000? and not subtract?

WebFirst you should find how many times 2.5 can go into 10, which is 4. After that you have 0.925 left to divide, but 2.5 isn't gonna fit in 0.925 so the decimal point has to go after the 4. Now you can use your other method to find how many times 25 goes into 925 which is 37. This makes your final answer 4.37. WebRules for expressions with fractions: Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100.If you use mixed numbers, leave a space between the whole and fraction parts.
