1 Let's write this in maths first: 10 div (1 div 0.1) 10 div 1/0.1 We can treat this as a fraction calculation or as a decimal calculation. As a fraction: To divide, multiply by the reciprocal: 10 xx 0.1/1 = 1 As a decimal, change the denominator into 1 10 div (1xx10)/(0.1 xx10) =10 div 10/1 =10 div 10 = 1
See below: >Finding 1/10 of a number is the same as dividing it by 10. To find a tenth of something simply multiply it by 1/10 and then simplify. That will be a tenth of it: What is 1/10 of 20? 20 can be put over 1, since anything divided by 1 is itself. So do that and multiply: 1/10 xx 20/1 rarr 20/10 rarr 2 Here are a couple more examples: What is 1/10 of 45? 1/10 xx 45/1 rarr 45/10 rarr 4.5 ...
Operation of dividing by 0 is undefined, which means that the question has no answer. Operation of division is DEFINED as follows: Real number C is called a result of division of real number A by real number B if and only if B*C=A. Assume, B=0. If A is non-zero, there is no such real number C that, if multiplied by B=0, gives non-zero A since the result of multiplication by 0 is always 0 ...
10 You have to use decimals, or fractions. ... What is ½ divided by 0.05? Algebra Properties of Real ...
You can split the fraction as it follows: \\frac{1.1 * 10^22}{6.022 * 10^23} = \\frac{1.1}{6.022}\\ \\frac{10^22}{10^23} and deal with the two parts separately. \\frac{1.1}{6.022} is a common numeric division, and the result is 0.1827 As for \\frac{10^22}{10^23}, you can see it in two ways: either you expand the powers, having a fraction of the form \\frac{10 * 10 * ... * 10}{10 * 10 * 10 ...
This operation does not change the value of your fraction because #sqrt2/sqrt2=1# anyway and your fraction does not change by multiplying #1# to it. Now you can multiply in the numerator and denominator:
2/5=4/10=0.4 We know that a negative divided by another negative will equal a positive, so we can ignore the negative signs. Let's use 5/2 instead of 2.5 1/1 divide 5/2=2/5 To convert to a fraction, we can set the denominator equal to 10. 2/5=4/10=0.4
8 This is asking how many groups of 10 can be made from 80. We can also do this by subtracting 10 until we get to 0, and count how many times we subtracted . 80-10-10-10-10-10-10-10-10 = 0 We subtracted 10 eight times. Division is a short cut for repeated subtraction. 80 div 10 = 80/10 = 8 The opposite would be 8xx10 = 80 Or 10+10+10+10+10+10+10+10 = 80
What is #1.5# divided into #3?# means the same as #3# divided by #1.5# #3 div1.5 =3/1.5# Multiply by #10/10# to get rid of the decimal in denominator. #(3xx10)/(1.5 xx10) =30/15 =2# ~~~~~ However, it might be understood as:, #1.5# divided into #3# 'groups' or into #3# portions. In this case it would mean #1.5# divided by #3# #1.5/3 = 0.5#
#P(1)=2⋅1^2−1−1=0#, so #x−1# is a factor of #P(x)# by the factor theorem. Once you have a factor, you can proceed with long/synthetic division to get your quotient. Then you will need to repeat and factor the quotient. Again, if it is a quadratic, switch to your quadratic factoring methods.
