Question

HELLLLLLLLLLLLLLLLLLLPPPPPPPPPPPPPPZZZZZZZ!!!!!

Answer 1

hint:
Please, compute this quantities, first:
\[\begin{gathered}
4\frac{2}{7} = 4 + \frac{2}{7} = \frac{{\left( {4 \times 7} \right) + 2}}{7} = ...? \hfill \\
\hfill \\
2\frac{1}{5} = 2 \times \frac{1}{5} = \frac{{\left( {2 \times 5} \right) + 1}}{5} = ...? \hfill \\
\end{gathered} \]

Answer 2

ok........

Answer 3

first one is 4.28?

Answer 4

please write the results as ratios

Answer 5

4/28.

Answer 6

hint:
we can write this:
\[4\frac{2}{7} = 4 + \frac{2}{7} = \frac{{\left( {4 \times 7} \right) + 2}}{7} = \frac{{28 + 2}}{7} = ...?\]
please complete

Answer 7

30/7?

Answer 8

yes! Next we have:
\[2\frac{1}{5} = 2 \times \frac{1}{5} = \frac{{\left( {2 \times 5} \right) + 1}}{5} = \frac{{10 + 1}}{5} = ...?\]

Answer 9

11/5

Answer 10

yes!
so we can write:
\[4\frac{2}{7} \cdot 2\frac{1}{5} = \frac{{30}}{7} \times \frac{{11}}{5} = ...?\]

Answer 11

= 9/42?

Answer 12

hint:
\[4\frac{2}{7} \cdot 2\frac{1}{5} = \frac{{30}}{7} \times \frac{{11}}{5} = \frac{{30 \times 11}}{{7 \times 5}} = ...?\]

Answer 13

330/35

Answer 14

correct!
now we have to reduce such ratio. In order to do taht we can divide numerator and denominator by 5. SO what is:
\(330/5=...?\) and \(35/5=...?\)

Answer 15

66
and
7

Answer 16

that's right, so the final result is:
\[\Large 4\frac{2}{7} \cdot 2\frac{1}{5} = \frac{{30}}{7} \times \frac{{11}}{5} = \frac{{30 \times 11}}{{7 \times 5}} = \frac{{{\mathbf{66}}}}{{\mathbf{7}}}\]

Answer 17

but you have to convert to a improper.

Answer 18

yes! Then please what is \(66:7=...?\) please wrie the answer without the decimal part

Answer 19

write*

Answer 20

wait, what do the two dots mean?

Answer 21

I asked the result of this division: \(66/7=...?\) I have used this symbol \(:\) instead of \(/\)

Answer 22

shoot.

Answer 23

quotient is...?
remainder is...?

Answer 24

ok, i had to calculate it, and i keep on getting 9.42.

Answer 25

therefore quotient is 9, so we get \(9 \times 7=63\) and remainder is \(66-63=3\) am I right?

Answer 26

yes.

Answer 27

so, the requested answer is:
\[\large 4\frac{2}{7} \cdot 2\frac{1}{5} = \frac{{30}}{7} \times \frac{{11}}{5} = \frac{{30 \times 11}}{{7 \times 5}} = \frac{{66}}{7} = {\mathbf{9}}\frac{{\mathbf{3}}}{{\mathbf{7}}}\]

Answer 28

thx.

Answer 29
