Hi Katie-Leigh,
I like seeing you one the forum. :)
I am not sure if you understand. It is good to say thank you but if you do not really understand it is very important that you say so. :D
One and 7/10 is 6 and 4/5 of what number?
Just give the unknown number a letter untill we work out what it is. N is good :)
so the question becomes:
One and 7/10 is 6 and 4/5 of N?
of means times so we have
One and 7/10 is 6 and 4/5 x N?
\(\frac{7}{10}=6\frac{4}{5}\times N\\ \frac{7}{10}=N\times 6\frac{4}{5}\\ \)
Now the opposite of multiply is divide so to get N all by itself you will need to divide by that mixen numeral
\(\frac{7}{10}\div 6\frac{4}{5}=N\times 6\frac{4}{5}\div 6\frac{4}{5}\\ \frac{7}{10}\div 6\frac{4}{5}=N\\ N=\frac{7}{10}\div 6\frac{4}{5}\\\)
You can finish it on the calculator or by hand :)
Do you completely understand?
If you don't, try and explain what is bothering you about it ..........................
Convert the mixed fractions into just fractions. Ex. one and two thirds = 5/3. "is" means equal, and "what number?" would be an unknown variable x.
One and 7/10 is 6 and 4/5 of what number?
1 7/10=17/10
6 4/5=34/5
Let the number be N
17/10N=34/5, solve for N
