Answer:
Gabe worked for 6 2/3 hours and Paula worked for 4 hours.
Step-by-step explanation:
It is given that,
Diana worked on her science project for 5 1/3 hours.
Gabe worked on his science project 1 1/4 times as long as Diana.
Paula worked on her science project 3/4 as long as Diana.
Solution,
ATQ,
Gabe worked for :
![5\dfrac{1}{3}\times 1\dfrac{1}{4}\\\\=\dfrac{16}{3}\times \dfrac{5}{4}\\\\=\dfrac{20}{3}\ h\\\\=6\dfrac{2}{3}\ h](https://tex.z-dn.net/?f=5%5Cdfrac%7B1%7D%7B3%7D%5Ctimes%201%5Cdfrac%7B1%7D%7B4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B16%7D%7B3%7D%5Ctimes%20%5Cdfrac%7B5%7D%7B4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B20%7D%7B3%7D%5C%20h%5C%5C%5C%5C%3D6%5Cdfrac%7B2%7D%7B3%7D%5C%20h)
Pauls worked for :
![\dfrac{3}{4}\times 5\dfrac{1}{3}\\\\=\dfrac{3}{4}\times \dfrac{16}{3}\\\\=4\ h](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B4%7D%5Ctimes%205%5Cdfrac%7B1%7D%7B3%7D%5C%5C%5C%5C%3D%5Cdfrac%7B3%7D%7B4%7D%5Ctimes%20%5Cdfrac%7B16%7D%7B3%7D%5C%5C%5C%5C%3D4%5C%20h)
Hence, Gabe worked for 6 2/3 hours and Paula worked for 4 hours.
I believe that the answer is 0.02329075882
0.27 is a multiplicative inverse because the product of
and
is 1
A multiplicative inverse is a number in the form 1/x which gives 1 as the result when multiplied by x. It can also be referred to as the reciprocal
That is:
![x \times \frac{1}{x} = 1](https://tex.z-dn.net/?f=x%20%5Ctimes%20%5Cfrac%7B1%7D%7Bx%7D%20%3D%201)
Express 0.27 as a fraction
![0.27 = \frac{27}{100}\\](https://tex.z-dn.net/?f=0.27%20%3D%20%5Cfrac%7B27%7D%7B100%7D%5C%5C)
If ![\frac{1}{x} = \frac{27}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D%20%3D%20%5Cfrac%7B27%7D%7B100%7D)
![x = \frac{100}{27}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B100%7D%7B27%7D)
Multiply x by 1/x
![\frac{27}{100} \times \frac{100}{27} = 1](https://tex.z-dn.net/?f=%5Cfrac%7B27%7D%7B100%7D%20%5Ctimes%20%5Cfrac%7B100%7D%7B27%7D%20%20%3D%20%201)
Since
, then 0.27 is a multiplicative inverse
