Answer:
![\frac{7}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B15%7D)
Step-by-step explanation:
To find the reciprocal of a fraction, simply switch the numerator and denominator.
Since
is a mixed number, start by converting it to a common fraction using ![a\frac{b}{c}\implies \frac{a \cdot c+ b}{c}](https://tex.z-dn.net/?f=a%5Cfrac%7Bb%7D%7Bc%7D%5Cimplies%20%5Cfrac%7Ba%20%5Ccdot%20c%2B%20b%7D%7Bc%7D)
Therefore,
as a common fraction is:
![\frac{2\cdot 7+1}{7}=\frac{14+1}{7}=\frac{15}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ccdot%207%2B1%7D%7B7%7D%3D%5Cfrac%7B14%2B1%7D%7B7%7D%3D%5Cfrac%7B15%7D%7B7%7D)
Now switch the numerator and denominator to find the reciprocal:
![\rightarrow \boxed{\frac{7}{15}}](https://tex.z-dn.net/?f=%5Crightarrow%20%5Cboxed%7B%5Cfrac%7B7%7D%7B15%7D%7D)
Answer:
75 coloured pencils
Step-by-step explanation:
Let's say Jordon has x total pencils.
We know that 20% of these x pencils is 15, so we have:
20% * x = 15
Remember that % is just "out of 100", so 20% = 20/100 = 0.20. Then:
0.20x = 15
x = 15 / 0.20 = 75
Jordon has 75 coloured pencils.
Answer:
