Find HCF and LCM 100 60

Mathematics

Answer:

HCF: 20

LCM: 300

Step-by-step explanation:

This is a simpler and easier way to answer this question. Refer to the picture.

Put the numbers (two or more numbers) side-by-side, then find a common factor. Put the factor on the right (2 in this case) and divide both numbers by the factor, then put the quotients below their respective dividends. Keep going until there are no more common factors. Then, for the HCF, use only the number on the left (i.e. 2, 2, and 5). Multiply them to get the HCF. 2*2*5=20

For the LCM, multiply the numbers on the left and the bottom, i.e. 2*2*5*5*3 = 300

100 = 2 \times 2 \times  5 \times 5 \\ 60 = 2 \times 2 \times 3 \times 5 \\ hcf = 2 \times 2 \times 5 = 20 \\ lcm = 2 \times 2 \times 5 \times 3 \times 5 = 300

nordsb [41]

define the 3 numbers

smallest number = x

middle number = x + 2

largest number = x + 4

write the equation

sum of the smallest number and twice the middle number

\begin{gathered} x+2(x+2) \\ x+2x+4 \\ 3x+4 \end{gathered}

20 more than the largest number

\begin{gathered} x+4+20 \\ x+24 \end{gathered}

equal the expressions

\begin{gathered} 3x+4=x+24 \\ 3x-x=24-4 \\ 2x=20 \\ x=\frac{20}{2} \\ x=10 \end{gathered}

the numbers should be 10, 12 and 14

\begin{gathered} 10+2\cdot(12)=14+20 \\ 10+24=34 \\ 34=34 \end{gathered}

What is the number sentence for "1 less than N is the sum of Z and<br> 2"?
s344n2d4d5 [400]

          \rule{50}{1}\large\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}

        <em>What is the number sentence for "1 less than n is the sum of z and 2?"</em>

<em> </em>

<em>          </em>\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}

  ❖ First, Notice it says "1 less than n". This expression indicates that

        we subtract 1 from n, which  looks as follows:-

                                                     \Large\textit{n-1}

❖ Now, It also says "the sum of z and 2". This indicates that we add z and

     2:-

                                       \Large\textit{z+2}

❖ Now, Combine these two little expressions into one equation:-

\implies\sf{n-1=z+2}

<h3>Good luck with your studies.</h3>
